It is attached to the board via two 15 pin female headers. Please help me to program an Arduino NANO with your software If you'd like further explaination, I'll update the Instructable. In case you missed it you can download the complete code here: pa3hcm_simple_iambic_keyer.txt. Total cost was under $25 What does it do? exit status 1 2. Morse code characters are all length six or less, and each element is either a dot or a dash, so it would seem that we can store the pattern in six bits. I had connected it to A6 because thats what these 79 year old eyes saw (or was sure they saw) when I looked at the schematic. At the end of the class we all had our own Arduino ISP adapter board and could burn a tiny85 by using an Arduino UNO as an intermediary. I would then also need to keep a number at the intersection of the row and column which would be the page number. Learn more about the CLI. You can buy crystals on ebay. First of all, I'd like to point out a few things. The K3GDS Keyer is a morse code keyer for Arduino. My work External handset/mic plug for your amateur radio. and if so delays the dotDelay. 1 /*By Nelson Farrier 2 Key up radio and send tone 3 Keys up Baofeng 4 UV-3R radio by turning on and off the relay, then ID's and and sends a 5 second 5 tone. The values one gets from analogRead are rather unusable as is even after scaling down by 2. Adafruit Mini I2C, Tutorial: Magic AI Storybook with ChatGPT and. Now that that's out of the way, let's begin! 7 to 12 Volts can be used. If you want to implement that, things get a bit more complex. signal from the key. You signed in with another tab or window. Keyer on Arduino 5. keyAndBeep(speed*3); // send a dash ay the given speed k3ng is a relatively cheaper open-source keyer that's Arduino-based Morse Code /CW with excellent flexibility and several features. But paddles dont create dots and dashes on their own, so you need some electronics, called a keyer. Stop breadboarding and soldering start making immediately! Tks a lot your easy arduino keyer project. Please note that operating a cw transmitter generally requires a ham radio license unless you terminate the transmitter with a dummy load resistor to keep from propagating a signal outside of your house. It comes with capacitive touch paddles, but also supports external paddles and an external straight key. Hi, you say you use the blue wire to key the radio. ik zit op dit moment in het buitenland maar ik kom binnenkort naar nederland, Join us every Wednesday night at 8pm ET for Ask an Engineer! The particular LCD keypad shield i sourced on ebay for about $7 had pin 11 and pin A3 free. 1 Analog input to read the speed from a potmeter. digitalWrite(P_CW, LOW); // Key up 2. Furthermore, you can use it with an AVR MCU chip/full-blown Arduino board, whereby you'll program and use it directly in circuits. I had the doors opened and the fan running. I quickly discovered the potential of such a keyer in the aid to learn Morse code. Thank you for taking the time to share your work! You could also shape the signal a bit using an RC circuit and feed a LM386 based audio amplifier, allowing you to attach a small speaker or headphones, but Ill leave that to you. #define P_DOT 2 // Connects to the dot lever of the paddle I browsed around the web trying to improve my programming skills, as this was probably the hardest code I had written to date. digitalWrite(P_AUDIO, HIGH); There was a problem preparing your codespace, please try again. digitalWrite(P_AUDIO, LOW); // Start with buzzer low Learn more about the CLI. This is completely optional and allows the keyer to be used without a computer.

More information on the map function can be found here: https://www.arduino.cc/en/Reference/Map Ik zag dat je een keyer gemaakt had met een Arduino. 73s, Ben, 73 de Dave GM4HPK, Nice job. Construction of the keyer is very similar to the Arduino Oscillator. // Authors: Keyer on MSP430 8. Thanks a lot, good job! Yes, its the blue wire and ground for most radios. Its easier than you think! digitalWrite(P_AUDIO, LOW); Ok, its probably the most expensive and specialized switch in your home, but still its a switch. Share it with us! pinMode(P_DOT, INPUT_PULLUP); Hi John This uses the PARIS method of 50 time units per word. The OTMK is a One Time Morse Key "game" for Ham Radio operators It can be used for send practice, and receive practice with Keyboard or Receive/Transmit Echo Practice. Morse "bug" keyer. Construction of the keyer is very similar to the Arduino Oscillator. // Read the keying speed from potentiometer and convert it to 10 to 30 WPM Indeed,finaly. // 60000 / (30wpm * 50) = 40ms, // If available, send new keyer data plus delay intervals, if(!digitalRead(P_DOT)) Very much how PA3CHM did it here: in his simple [], Hello, Ernest! This is not a very good keyer device, but it's a fun and easy place to start. You can download the keyer code from my GitHub repository to save you some time. Introduction This example is an implementation of a Morse code keyer, useful to Ham Radio CW operators using Iambic paddles (see Figure 1) to send Morse code. digitalWrite(P_CW, LOW); // Key up If you don't use the built-in LED, the pin value to change is, If you use a normally open button for memory, you will need to invert. Have an amazing project to share? document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); This site uses Akismet to reduce spam. Tap the button (for less than 1 second) to stop recording and tap it again to play back the saved message. Your email address will not be published. // 60000 / (20wpm * 50) = 60ms Thanks again worked right off. THats what started me on building Arduino keyers. In the future I intend to experiment with a keyer with ATMEGA 2560. Its fun to do, and you learn new things. for (int i=0; i < (speed/2); i++) // Beep loop Then a for loop runs for a while, all statements within this loop are repeated lots of times, depending on the value of the speed variable (so the setting of the potmeter). Adafruit publishes a wide range of writing and video content, including interviews and reporting on the maker market and the wider technology world. The code can be used with a full blown Arduino board or an AVR microcontroller chip can be programmed and used directly in a circuit. Step 1: What Is a Iambic Morse Key? For that something more permanent than sa breadboard build was necessary. In the Arduino software, go to the menu: File > Examples > LiquidCrystal. After reading pages after pages, you're ready to do it! Simple Iambic Keyer v1.00.. Hi, you can delete this two resistors pull up, replace: pinMode(P_DOT, INPUT); once I fixed that error, the keyer works perfectly.the unstable characteristic of the keyer went away.. I'm Dan, from Belgium I'm a Fourteen-years-old tech fanboy. keyAndBeep(delay_for_wpm); https://km4nmp.com/2019/03/31/arduino-morse-code-practice-oscillator-project/, https://km4nmp.com/2019/04/06/arduino-oscillator-with-morse-code-decoder/, https://www.arduino.cc/reference/en/language/functions/advanced-io/tone/. Still, it might add some links to such projects for inspiration. When high (+5V), the key is pressed. Get the only spam-free daily newsletter about wearables, running a "maker business", electronic tips and more! Try severals parts os LCD programs (like Hello World) but nothing works. In July 2013 Jim Williams from Workshop 88 in Glen Ellyn conducted a class in tiny85 programming which I attended. delay(delay_for_wpm); Keyer on ChipKit 7. Have just one problem, currently it works in Mode A Good luck! via wb8nbs Richard Chapman KC4IFB published an article in the Sep/Oct 2009 QEX magazine (subscription required) for constructing an Iambic Keyer on "); break; case 'f': tx("..-. Chris ZS1CDG built a slightly different version, which is a touch paddle. delay(1); } // Simple Iambic Keyer v1.00 { Zag je naam voorbij komen in een mailtje van Aeilko van der Wagen (de enige andere ham van Soesterberg, hi) digitalWrite(P_CW, HIGH); This meant holding a variable for the column number, a variable for row number, both of which to be looped around or limited. accidental programming while the Arduino Nano is in the keyer board. I could never set aside the time to learn the basics. arduino. Nano could easily be used for other purposed. Yes Antti, the speed adjustment is far from perfect, however I tried to keep the code as simple as possible, to allow starters to understand the code. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. Once youve tried it your way, head over to the web and see how the programmers do it! About: I am an American teaching English at Shangluo University, Shaanxi. This will require a bit more code, since then you have to determine if both levers were pressed. Add an Ethernet Shield to the Arduino and enable keying over your local network. ^~~~~~~~~~ 3. }, void keyAndBeep(int speed) { if(!digitalRead(P_DOT)) // If the dot lever is presssed.. Arduino IDE. Anttis version of the code can be downloaded here: https://github.com/andyn/iambic. the problem was me! After the manual implementation of the program I did the Upload but it did not succeed, the error appearing below: 1. -Thanks-. For example; // here is where the setup will be // here is where we will define all the variables // This is the routine that converts a letter into dits and dahs // this is where the menu code will live And so on. We define constants for all pins used, and also introduce a variable (integer) to store the value of the potmeter, called speed: The next step is the setup routine. Well it can send morse cqs or any morse message to the onboard piezo or the relay for connection across a radio key. I used the generation two and generation three versions for this but for my winter 2016/2017 Arduino project, I decided to build a version that is solely intended for code practice and would fit in a shirt pocket. So thats pretty much how the code goes. Arduino Practice Keyer v2 Anthony (K3NG) has created the feature rich keyer software that I've been using as well. 73, Ernest PA3HCM, [] that change on pins 10 and 11 and send the dit and dah accordingly. Yes, they are! Change), You are commenting using your Facebook account. I suggest that you first build your prototype on a breadboard, at least I did for this article. Hopefully you or someone who reads this post can help me. Total cost was under $25 What does it do? Good luck! To start recording, hold down the memory button for at least 1 second. You may use the build-in keyer of your radio, but most of them lack of functionality. pinMode(P_CW, OUTPUT); if(!digitalRead(P_DASH)) // If the dash lever is pressed { digitalWrite(P_AUDIO, HIGH); delay(speed); // 40ms to 120ms x 3. ie 360ms, // Output lines off Thank you so much Ernest, Hi Ernest, // Key the transmitter and buzzer The code can be used with a full blown Arduino board or an AVR microcontroller chip can be programmed and used directly in a circuit. The code to run is as follows (download the Arduino software here ): 1. I believe in trying to do it your self, so you can learn first. This it it, last step before testing! // by Ernest PA3HCM, void loop() { I use a PN2222 NPN transistor with a 50K ohm resistor. It appeared so simple and yet when I loaded in your sketch, it almost worked the first time. #define P_DASH 3 // Connects to the dash lever of the paddle This is a great use of an arduino! Congratulations, Youve just finished the prototype of your keyer! Today we will build a Basic Arduino Keyer. Maks UT3UEZ used it in a morse trainer/simulator, using an Arduino Mini. { Create a memory keyer, the Arduino has an internal EEPROM where you can store your messages. The project is simple enough that any amateur radio operator should be able to build one, even without previous Arudino experience. Then, I'd really appreciate if you could point out the things I should improve for my next Instructable. Adafruits Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Here are some ideas to extend/personalize your keyer: As always for any questions or comments regarding this article just place a comment down here, or use the contact form on this website to send me a private email. https://github.com/k3ng/k3ng_cw_keyer/wiki. Yuri EW6X, Hi, nice project! void setup() If nothing happens, download GitHub Desktop and try again. A tag already exists with the provided branch name. Then i hot glued everything to everything! pinMode(P_AUDIO, OUTPUT); If you have never programmed an Arduino before, you might first take a look at some examples, starting with this one: File Examples Basics Blink. Also,I Strongly recommend you keep your Arduino unplugged while doing the wiring. I'm not going to teach you the history of morse code, nor am I going to teach you morse in general. The code can be used with a full blown Arduino board or an AVR microcontroller chip can be programmed and used directly in a circuit. Added a semi auto option and now able to use homebrew cootie to mimic. Zoek even op nanokeyer, en je ziet vazelf de links naar de keyersoftware. digitalWrite(P_CW, LOW); // Start with key up Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. 8 years ago Iambic mode B has nothing to do with that, it has anything to do with what to do when both levers are pressed simultaneously. keyAndBeep(speed*3); // send a dash ay the given speed My note:the program has been blockt here telling : keyAndBeep was not declared in this scope ! In this montage, a blue light will mean a "Diht" or "Point" and a red one will mean a "Dah" or "Dash". I modified the speed setting as per Antti above but modified it a little to read better by defining Maximum_speed_WPM, and Minimum_speed_WPM early on. The green light is a signal, signaling that a key has been pressed. Are you sure you want to create this branch? Invalid version '2021.12.16.01' for library in: C:\Program Files (x86)\Arduino\libraries\K3NG_PS2Keyboard pinMode(P_CW, OUTPUT); I had left off the pull up resistor as I was not sure they were needed. sign in digitalWrite(P_CW, HIGH); // Key down pinMode(P_DASH, INPUT); with: }, void loop() { The CWvox is a simple device that converts voice commands into Morse code keying While most of us associate Morse code with old-timey telegraphs, it is still in use today. I've attached the code that i have come up with, if you improve it let me know! OBS: I think it would be good to delete the pages with the big problem of uploading software from Feb 9, 2022 / 12:30. The servo signal wire goes to digital pin 5, the power goes to 5 volt and ground to ground. So why not build your own keyer? This worked out quite well. When you release the button, an LED will turn on to indicate that recording is active. ': dit(); break; case '-': dah(); break; delay(Spaces); // pause between characters, // *** Characters to Morse Code Conversion *** //, // Take the passed character and use a switch case to find the morse code for that characters, // NOTE: have to terminate parameter with space (or just slash if you want - I uses spaces for readabilty)-. I bought the PC board from WB4VVF himself at the Dayton Hamvention. digitalWrite(P_AUDIO, LOW); The arduino also provides pins labelled GND (for the ground connection of the keyer) and 5V (for the pull-up resistors). I came across the NanoKeyer website, looked at the schematics and build this very simplistic keyer. Adafruit IoT Monthly Guardian Robot, Weather-wise Umbrella Stand, and more! I used this line; speed = 60000 / (map(analogRead(P_SPEED), 0, 1023, Maximum_speed_WPM, Minimum_speed_WPM) * 44). // Increment to the next element in the array, // modified from: Mike Myers (http://mikemyers.me) @netnutmike, // Input: Character that should be either a dot or a dash, // This function first turns on the output then looks to see. You shouldn't do a lot of damage if you do something wrong here, but it's frustrating to fix! Learn more about the CLI. { // If the character is not a "." { delay(1); Several posts back, we made an Arduino Morse code oscillator. The code can be used with a full blown Arduino board or an AVR microcontroller chip can be programmed and used directly in a circuit. 5)-Internal beeper for learning purposes. Paddles come in different shapes and sizes. { I almost understand your sketch. [ Hits: 369 | Votes: 0 | Rating: 0 ] The ArduinoNano is the core/brain of the keyer. keyAndBeep(speed); // send a dot at the given speed This prevents from switching the polarity by accident. on Introduction. James Harvey made an Arduino based iambic keyer. If you use pinMode(P_DOT, PULLUP_INPUT); you can remove the external pullup resistors and use the internal ones , I applied external pullup resistors, so INPUT is ok then. then the routine assumes it, // is a "-" and keep the output high for 3 times the length of, // dotDelay. It's exactly the same process, except for the last wire. Any serial terminal application works on your computer. We use this to define which pin is an input or an output, using the pinMode statement. Ive seen others solving this issue by adding series resistors on both sides of the potmeter, which is actually the physical way of implementing the map() function Please Error: Now the routine returns to the first statement, reading the value of the potmeter again, checking the dot lever, etc. Couldnt afford the $$$$ price wanted for a vibroplex.

I did manage to get it working but wondered if there was a smarter way to go about it. // 512 * 0.02 = 10.xx Add 10 = 20 WPM The keyer software consists of 4 parts: We start with the declarations. So when not pressed, a 1 should appear at the Arduinos input, so we add a 10k pull-up resistor to each contact, connecting it to +5V (operating voltage of the Arduino). Invalid version '2021.12.16.01' for library in: C:\Program Files (x86)\Arduino\libraries\K3NG_PS2Keyboard But this is just a very basic keyer. // At the end of the sequence, there is a delay of 3 times, // Increment to the next element in the array, // Input: Character Array of text in English. But by far, I love to listen to music,, How to Make a Voltaic Pile - the World's First Battery, AI-assisted Pipeline Diagnostics and Inspection W/ MmWave, ECLIPSE - the Ring Lamp With Progressive Lighting, IR Controlled. A lambic morse key, or dual-lever morse key is basically a morse key with (wait for it..) two paddles. The Arduino runs this code only once, at start/boot time. The K3NG Keyer is an open source Arduino based CW (Morse Code) keyer with a lot of features and flexibility, rivaling commercial keyers which often cost significantly more. Required fields are marked *. Pretty simple and effective sideswipe key.

While Adafruit is not an independent journalistic institution, Adafruit strives to be a fair, informative, and positive voice within the community check it out here: adafruit.com/editorialstandards, Adafruit is on Mastodon, join in! But, if you still want to learn about it, I recommend you go read a few lines on the Wikipedia Article. { delay(speed); // and wait before sending next Work fast with our official CLI. Documentation is located here: Saddly, the most complicated one. I have a WB4VVF Accu-Keyer I used with my homemade paddles long ago. This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository. I think anyone can download the code from the QEX software page The benefits now are the same as they were a 150 years ago: it is an incredibly resilient way to encode information that works with a variety of different transmission methods. Subscribe at, on Ham Radio Morse Code Keyer With Arduino, Pride Month at the The New York Public Library, 2020 Extrusion End Cap #3DThursday #3DPrinting, Customizable Threaded Insert Practice Plate, New Products 5/24/23 Feat. Keyer on PIC32 6. my issue now is..the dots and dashes are not stable and vary in duration and time. This is a CW keyer based on Arduino UNO (for transmitting International Morse Code - telegraphy).It was designed to work width an iambic paddle and it has a . char stringToMorseCode[] = "cq cq de xxxx"; Adjust the 'dotlen' length to speed up or slow down your morse code, (all of the other lengths are based on the dotlen), (pause between dots and dashes within the character), Pause between characters = Dot length x 3. http://www.nu-ware.com/NuCode%20Help/index.html?m int dotLen = 150; // length of the morse code 'dot', int dashLen = dotLen * 3; // length of the morse code 'dash', int elemPause = dotLen; // length of the pause between elements of a character, int Spaces = dotLen * 3; // length of the spaces between characters, int wordPause = dotLen * 7; // length of the pause between words, Servo myservo1,myservo2,myservo3; // create servo object to control a servo, int potpin = 0; // analog pin used to connect the potentiometer, int val; // variable to read the value from the analog pin, myservo1.attach(5); // attaches the servo on pin 5 to the servo object, delay(dotLen); // hold in this position, delay(dashLen); // hold in this position, myservo1.write(110); // move servo back to neutral position, delay(delayTime); // hold in this position, // Get the character in the current position. Did you make this project? kunnen helpen hoe kom ik aan zo een keyer? https://www.youtube.com/watch?v=J-2DsarAEOA Now connect the Arduino to your PC and upload the code. I recently decided to build another project, this time involving morse code and the arduino. 3) I'm still beginning in the amazing world of coding and electronic in general. Pressed one way the key produces a stream of dots, pressed the other way the key produces a single dash for each press. Thanks, I solved the problem by following your advice. So you must be connecting more than just the blue wire? Add one ore more buttons (use pull-up resistors, like done with the paddle buttons) to transmit standard texts, like your callsign or a CQ message. Altrough, I recomend you double-check your wires before pluging the Arduino on, you never know! Very simple and easy to follow. 73, Ernest PA3HCM, Ernest, Very impressive it seems to me.

The main component of the keyer is (of course) the Arduino board, and we will create the following inputs and outputs: The paddle contacts have to be translated to a digital 1 or 0. Work fast with our official CLI. I've been working with that sketch for a couple of years now and have two small projects I would like to present to this forum. and "-" and. keyAndBeep(speed*3); // send a dash ay the given speed We attach a transistor (almost any common NPN type transistor will do) to this pin. Therefore its functionality is very limited, but most people should understand the code. The paddle wires connect to pins 2 and 5. Much smarter,simpler and good enough for what i was trying to do here, keep it simple for me and if anyone else wanted to use it. The strip-board also simplified the wiring I had to do. They have 8K of internal flash memory and with a minor bit of library downloading, are programmable via the Arduino IDE. int raw_wpm = (analogRead(P_SPEED)* 0.02)+10; Downloaded and installed Arduino ide and Teensyduino. The 6.3mm stereo jack is used to connect a straight key or iambic paddle. I dont have a subscription but was able to see several articles about it just by googling. 1. It starts with keying the output, setting the P_CW pin to HIGH (5V). document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); A technology blog to show my creations and thoughts, to inspire others and to share the fun! Memory. Arduino: 1.8.19 (Windows 8.1), Board: "Arduino Nano, ATmega328P" Position 1: Produces the string "CQ" (calling for contact). The black wire to ground and the red wire to pin 11. "); break; case 'g': tx("--. keyAndBeep(3 * delay_for_wpm); Messages are translated automatically to Morse code. However, the build in speaker is nice to have. The red and black wires to the 1/8 connector (resistors, barrel) are +5V and ground (respectively). Add an LCD display showing the current speed. 4)-Reverse mode for left-handed operators. The main difference is the addition of the extra pin. These are great if you are only using a standard straight key. // for function tx to work. Initially i imagined a grid system of menus using up/down/left/right. Take a look at other Arduino-based keyers on the web and get inspired. C:\Users\daniel\Documents\Arduino\simple_iambic_keyer\simple_iambic_keyer.ino: In function 'void loop()': You may consider buying a starter kit, containing an Arduino board, a breadboard, and handful of parts (LEDs, switches, sensors, motor, servo, etc), wires, and a guide learning you the basics. Once uploaded the keyer will come to live immediately, since its powered by USB now. // 60000 / (10wpm * 50) = 120ms via wb8nbs. // the setup routine runs once when you press reset: // initialize the digital pin as an output. delay(1); k3ng Keyer Introduce. This could be improved by making sure the. All done on the hardware front. http://www.arrl.org/files/file/QEX%20Binaries/09_September/9x09_Chapman.zip I amped up my ISP adapter by adding a ZIF socket. replaced that and at last,the sketch compiled and uploaded.

Im not an expert on arduinos, s Im trying to update the project to have a simple 1602 LCD. Each contact is shortened to a common contact, normally connected to ground. Yuri EW6BN put his version into a small plastic mints box. If you want/need more detailed explaination, I'll update the Instructable! it works great. The code part is really simple. This keyer was purely exploratory. The main difference is the addition of the extra pin. The final part of the code does the actual keying and sounding. Hi all, Heres a better version. speed = analogRead(P_SPEED)/2; If you want more info check out my blog post here.. Did you make this project? } Invalid version '2021.12.16.01' for library in: C:\Users\daniel\Documents\Arduino\libraries\K3NG_PS2Keyboard, Hi Dan, } K3NG CW Keyer. If you want to experiment with other values, start by changing 40 to a lower (for higher speeds) or higher (for lower speeds) value. Morse code keyer for Arduino. If you have a shortwave radio without the SSB capability you will not be able to hear the side-tone. It goes in the pin 8 of the Arduino. I wanted to see if this code would run on an ATtiny85 chip. Thanks There have been ten revisions so far, each one adding more capability to the device, I hope the code can be improved further still. It's a perfect time to listen to the keyer's morse practice mode in headphones. 3)-Variable speed from 5 to 70 wpm. New Products Adafruit Industries Makers, hackers, artists, designers and engineers! Daniel VE7LCG, Thanks for such a nice keyer, needed something for my HW9 was able to put a volume and switch control in a very small box. Unauthorized use and/or duplication of this material without express and written permission from this sites author and/or owner is strictly prohibited. This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository. I added a 10uF electrolytic capacitor (C1) from the reset pin to ground. There's really not much to do here, just solder the piezo buzzer wires to the LCD keypad shield. I have had the PL600 and the PL660 and they are both great radios. Change). Replace the buzzer by a lowpass filter (to shape the square wave) and a LM386 based audio amplifier, so you can use a small speaker (sounds nicer) and/or headphones. You tell me where you put the line in the code created by Ernest? The real unit has a horizontal paddle type key which is pressed to the left or right [2]. And because the morse library takes care of timing and can send strings of morse characters, it was a rather prospect to add in a 4 button keypad, fiddle with the example code in arduino and get some memory functions happening. Project description Story: There are various styles of automated Morse keys the bug being one of the simpler [1]. Phew, 3 variables just to start with. First of all, if you came this far, I'd like to thank you, because it's my first Instructable. void keyAndBeep(int speed) Tune the radio near the crystal's frequency, in my case it was 7.159 Mhz. congratulation!!! Position 4: Produces a string of 6 randomly generated digits AKA the One Time Morse Key // put your main code here, to run repeatedly: 73, Ernest PA3HCM, Hallo Ernest Morse code keyer for Arduino. Morse Code Beacon Keyer - This circuit stores a morse code message as bits in an EPROM chip, the message controls a relay that keys a CW morse code transmitter. } // // if the character is a "." #define P_CW 13 // Output of the keyer, connect to your radio Are you sure you want to create this branch? // Antti OH3HMU I decided to look around the web. You can skip the external resistors and use the internal pullup resistors instead, but I found that less clear for educational purposes , Nice job! keyAndBeep(speed); // send a dot at the given speed to use Codespaces. "); break; case 'q': tx("--.- "); break; case 'r': tx(".-. He replaced both 10k resistors with 2M ones and uses his fingers as switches. The benefits now are the same as they were a hundred and fifty years ago: it is an incredibly resilient way to encode information that works with a variety of different transmission methods. // by Ernest PA3HCM. https://www.youtube.com/watch?v=cFADTW8faSA I'm going to try to make more Instructables, if you have any suggestions, feel free to post them, I'll be more than happy to read 'em and try 'em :D, About: Hey you! for (int i=0; i < (speed/2); i++) // Beep loop // character is a "-" but for most cases it would not matter. I quickly discovered the potential of such a keyer in the aid to learn Morse code. { Now Im going to play around with it until I understand it. Search for LiquidCrystal_PCF8574 and hit the Install button. This now gives a reasonably linear speed adjustment. This project takes an Arduino and uses it to key up the radio to transmit and then sends the station ID (the call sign of ham radio operator) using Morse code. It demos the morse alphabet. QEX issues are not available for download, but I once found a copy on the net by Googling. Ernest, an excellent simple iambic keyer project and the code is easy to read. This article gives you a decent start for such a keyer, by implementing the basic functionality and learn a bit about the Arduino platform if youre not familiar with this board yet. }, //, // Simple Iambic Keyer v1.00 How to make an Arduino Keyboard with Morse Code engineerish 2.35K subscribers Subscribe 228 9.3K views 4 years ago Why have a keyboard full of buttons when you only really need one?
