This is just a hobby and I have not written a lot of code for the Arduino. This program allows CW operators to copy CW code with a computer. Arduino Morse Code Decoder with Audio Biasing Circuit Arduino CW Decoder Sketch: https://pastebin.com/Yu0mm9Zq Goertzel algorithm: https://en.wikipedia.org/wiki/Goertze. SOS also has the most marks (dots and dashes) of any I found, so the sketch supports up to 9 bit characters. Projects. The KY-037 has a 100K potentiometer to adjust the threshold where the output triggers from high (nothing detected) to low (sound detected). Yes they can. Upload the sketch (Seinsleutel2.ino) in the Arduino. I am working for the Museum Engelandvaarders where we have a key from the 2nd World War. The code is also attempting to be smart and ignore really fast and really slow changes. Here is my CW / PSK31 / PSK63 decoder from 2010, drawing around 2mA current, doing audio filtering on a MSP430 with no HW multiplier. Firstly, it convert the text you sent it into morse, and emit it via pin 11 (you may want to connect to a potentiometer in serie with a buzzer). After quite a bit of coding, well lots more thinking than coding, I was able to get it display a single character on the screen with input from the Morse key. When it does not recognize a character, it buzzes the length of 4 dots then wait the equivalent of 2 dots, send an error message with the character it didn't recognized and its binary value on the serial, and replace the character with a "?" I was surprised to find out, that there is still interest in this first digital data transmission and that visitors have fun trying it. alan has updated the log for What is PoE? include Reply Perhaps it is changing at the frequency of the tone playing or at least at a ratio of the tone. . Any Morse it hears is displayed as plain text on a display. All seem to work ok. Im using the standard Arduino IDE. Moxon Antenna for 6 meters. Resultaten van 8 zoekmachines! With LCD display screen, the data is more clear. For example: . amateur radio, Arduino, cw, ham radio, morse, morse code. The other idea was to try a different library. Use it with something that emits Morse code as sound or vibrations. This should make up for some of my less efficient code J, To assist in setting the morse speed to ensure the timing is correct Ive used the dot length in milliseconds to convert to words per minute. Use a 20 x 4 LCD for simplicity. Magic Morse is implemented in a single microcontroller chip (PICAXE 20X2 -PIC18F14K22 uC), a wide band tone demodulator, and a Morse character decoder. Arduino Uno; 16x2 LCD display; Yellow LED; 10K potentiometer; Active buzzer; 2 buttons, breadboard and a lot of jumper wires; Features. Ian liked CH Products Trackball Pro USB modding. Once you have that limitation, why use Morse code at all? Usage. LCD Display: Arduino microcontrollers can be hooked up to a Sainsmart 128x4 LCD display to display information from the Arduino. I was expecting the digital output would change when the audio tone of a beep was detected and change back when the tone ended. I tried adding a smoothing capacitor as they have in power supplies. zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz Traditionally, youd have an audio filter and detector, maybe some agc or limiting, external to the computer. The Hitachi-compatible LCDs can be controlled in two modes: 4-bit or 8-bit. C:\Users\xxx\Desktop\HAM\Arduino CW ID\Arduino-Morse-Code-Decoder-master\Arduino-Morse-Code-Decoder-master\MorseCodeDecoder\MorseCodeDecoder.ino: In function void displayMark(char): MorseCodeDecoder:650:5: error: lcd was not declared in this scope, lcd.setCursor(d, 3); // Set cursor to correct place on the last line. In my opinion, the glowing backlight seems to have the right aesthetic for the project. . That method of filtering the incoming audio is not ideal. The speed potentiometer can be set on the border of different speeds and the display flickers between two different speed numbers. To increase the flexibility a microphone like this can be added to the circuitry. By far, the most tried and used Arduino CW decoder project can be found here: http://www.skovholm.com/cwdecoder It first uses a variation of the Goertzel formula to detect the actual audio CW tone so you can hook your device right up to the radio with very minimal components, then it uses a look-up table to match characters to display them. Hi Gerry, { if (tijd > StreepDuur / 3.0) StreepDuur++; if (tijd < StreepDuur / 3.0) StreepDuur--; } kar += teken; //Serial.println(teken);}void DecodeerPauze(long starttijd) { if (kar == "") return; char teken = '? While Morse code operators usually rank their skills by speed the faster the better this Morse code projectfor very low power transmitters turns that notion on its head by using speeds more suitably measured in minutes per word (77 MPW for that project). This is what I saw when I connected it up. Can you give me any advice about how to modify the code ? The case has built from some old timber. One can also enter a English phrase on the serial monitor and have the LED light up with the corresponding Morse code flashes. I recommend checking that you have the correct library selected and grabbing the Morse Decoder code again from GitHub and trying to compile it as is and see if you get any errors. I connected it to an LCD module and an Arduino Nano. De bezoeker mag straks letter voor letter morsecode nadoen in de hoop dat er wat leesbaars op het scherm komt. If I was doing it again I would try soldering a 10k pot and another resistor (maybe 39K) in series with the onboard pot as that would be much easier to wire up. const byte LCD_ROWS = 4; I have to confess Im not sure what is causing that error. estudihambre May 24, 2022, 6:16pm #13 Morse code is used in telecommunication; it is a method of transmitting and receiving coded information. In the end I experimented with the output connected to an oscilloscope and Morse playing into the mic. Change), You are commenting using your Twitter account. What is heard in the small lautspeaker is a sound generated only as a function of a decodet signal. (Imagine a motor spinning a drum synced with the baud rate, and the incoming bits trigger what part is facing the paper, followed by the whack of the hammer when the last bit is decoded.) That made it far easier to use and placed the threshold setting at about the midway point. // ********************************** LCD library and setup ********************************* Add Tip Ask Question Comment Download Step 1: Requirements 1x Arduino UNO I was expecting significant code changes to get it to work, but instead I only needed to change a few lines at the start of the sketch. If follows along with changing speeds ok, but it sometimes adds spaces when it shouldnt, it also has trouble if it quickly changes for example when it switches between to senders that are using very different speeds. This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository. That's a two-module chronometer for your MTB (or any others sports) to measure your time in a determined circuit! Ive included the reverent section of the code and the error. C:\Users\xxx\Desktop\HAM\Arduino CW ID\Arduino-Morse-Code-Decoder-master\Arduino-Morse-Code-Decoder-master\MorseCodeDecoder\MorseCodeDecoder.ino: In function void welcomeScreen(): MorseCodeDecoder:521:3: error: lcd was not declared in this scope. Sending Morse using appropriate timing, even slowly is much harder than I expected. The compiler just converts them to numeric tokens and compiles them as defined. Other parts should be common components or modules and not many of them. https://www.youtube.com/watch?v=2Aydo8dUZjM, Source code on the LCD screen. The decoder will receive Morse code from an audio source, decode it and display it on a built-in 4 line, 20 character LCD. A good result. We would like to see this hooked up to a proper Morse code key, and see how fast [Rostislav] could drive it before it conks out. Hjalmar published the schematics and source code for everyone to use. Morse code reader, translator. Circuit: Morse code with Arduino. This library gives the Arduino finer-grained control over the morse code that it is sending while it is in the process of sending it - that is, sending morse code is a letter-by-letter process, not a string process. Arduino Uno, and a 16x2 LCD module. ARDUINO MORSE DECODER LCD DOWNLOAD Here you can download the code : Download version 1.1 Right click on the mouse and chose save as. It's a Morse code receiver base on processing the light signals. Volume threshold. Flowerpot Antenna for 6 meters. The first was to remove the I2C backpack from the display and connect it up directly to the Arduino. LiquidCrystal lcd(rs, en, d4, d5, d6, d7); Yep. Description You know how it is; you're a long time CW Operator and your speed is OK (18-25WPM) but you just can't stretch up to the manic speeds sometimes used in contests or by 'DX' stations. Ham radio essential CW decoder. I saw a few papers but no actual project so far :(, And this will turn your voice into Morse Code. In designing the decoder I wanted to achieve: The project was partly about trying out some ideas with the case as well as the actual unit. SPST switch for power on/off. While it could do with a bit more development and tweaking, it is now at a point that it works reasonably well, at least where the audio doesnt have too much background static and hiss. I want to use the hd44780 library and my LCD doesnt have a backpack. zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz I removed the potentiometer and replaced it with an 10K pot and 22K resistor in series. This is probably the simplest decoder possible, and thus its logic is pretty straightforward to follow. Tip: you could create it without an LCD and then output the decoded text on the serial monitor of the Arduino IDE. I decided to try two methods to speed it up. (LogOut/ Pot to adjust the audio threshold. The maximum length of a dash is set on line 367 with the maxDashDuration variable. Place the microphone in front of the speaker sounding the Morse, Adjust the input sensitivity so that the audio LED flashes in time with the sound of the Morse, For manual operation, set the function to Manual, Look at bottom line of the display and adjust the speed pot so that it is displaying both dots and dashes in the pattern I hear, Look at the received and set speed numbers on the top line of the display and adjust so the set number is similar to the received number. 4 years ago, the code inside the .ino file. I suspect there is less clearing and overwriting text. Ik ben bezig voor het Museum Engelandvaarders waar we een seinsleutel hebben uit de 2e wereldoorlog. I am studying your source code and I have a question about the algorithm you use to identify a Pause and start decoding the "Kar"achter. Step 1: Select Mode any One By defoult Select first option.. "/> Hardware Required Arduino Board It is fiddly to use so adding one in parallel makes it much easier to use. I used a standard 10K linear pot. 11.9K subscribers Audio from a lap top computer sending Morse Code is fed into an Arduino Uno that decodes tones and prints characters on an 20x4 LCD display. With a key you could try removing those. > S I wonder if what you are seeing is bounce? https://hackaday.com/2020/07/16/speech-to-morse-code-courtesy-of-google/, Please be kind and respectful to help make the comments section excellent. Arduino Morse Decoder: This device reads hand keyed Morse code from a signal key (or an ordinary switch) and translates it to plain text and show the Morse code you're keying on an LCD. In Ham Radio magazine in later 1971, there was a CW decoder done without a computer, I cant remember if it used ICs. I tried to improve the speed in the rest of the sketch as best I could, but Im sure it could be improved further. Dcoder du morse avec un arduino Dcoder du morse avec un arduino L'alphabet morse ou code morse, est un code permettant de transmettre un texte l'aide de sries d'impulsions courtes et longues, qu'elles soient produites par des signes, une lumire ou un geste. You could try adding those to start with and see how that goes. Morse Code Sound & Vibration Listener. I recently decided to build another project, this time involving morse code and the arduino. Im not a professional or have professional experience. I set myself a challenge to design one. Morse code was developed in the 19th century to send messages over long distances using very simple sequences of long and short pulses, commonly referred to as dots and dashes. Share it with us! Its structure could be improved. You signed in with another tab or window. Demo video: https://imgur.com/gallery/UQBnXUy. Well thats up to you, but Ill repeat what I said early on. Ask Hackaday: Will Your 2030 Car Have AM Radio? I love how neat and simple it is! We will use Morse's encoding and by using 2 buttons (dot & dash) we will write down the letters into a display. You could try increasing that value. Ill say straight up that I am not a developer or have electronics training. Not only that but the display seemed clearer. The decoder to use a microphone as the input. But with a more relaxed setting it is working now. 3 years ago, "Nice project, I'm going to try this out. ************** I started with a simple Morse key that I made from a piece of scrap timber, bending a piece of metal strapping from around the packing of some large item we had purchased, a few screws and an old knob. 1 x LED to replace the one on the audio module. 1x Arduino UNO 1x Buzzer1x LCD with I2C connector and 4 lines of text. Besides the GND and +5V pins the LCD has an SCL and SDA connection that you connect to the pins with the same names on the Arduino. Thanks!!! There is a spectrum display of the audio with a sliding cursor to select a particular audio for decoding. This project uses a 567 Tone Decoder IC to filter out unwanted audio and feeds a clear signal to the Arduino for real time decoding on the ( XC3728) OLED screen. For displaying text on the screen, you can do most everything in 4-bit mode, so example shows how to control a 16x2 LCD in 4-bit mode. This device reads hand keyed Morse code from a signal key (or an ordinary switch) and translates it to plain text and show the Morse code you're keying on an LCD. Part of the build was trying to come up with a simple to build and interesting project enclosures. Project showcase by Gabriele Scordamaglia. Download the file-> open the arduino IDE -> file-> open-> chose the file that you had been downloaded. Well the speed of the whole sketch probably becomes significant. If you are. 10K linear pot to adjust contrast of the display. ex. Used a strip printer for output. While it works ok, manual mode holds the speed to a more stable setting. Building projects is just a hobby for me. Windows IDT High Definition Audio CODEC EZ CD Audio Converter Free to try Convert audio files, rip. At the very least I hope the project gives you inspiration. The core processing unit was based on a with a plastic knob on top of it and an adjustable contact low cost ATMEGA328P microcontroller, embedded with underneath. The object of the cache would be for the finder to translate a specific word into the dots and dashes of morse code. Hi Peter, thanks for your interest in the project. CW Morse Code Beacon Keyer or Ident . Learn how your comment data is processed. Auto mode that automatically tracks sending speed. Type Morse code on Arduino and display it on your computer's monitor. The problem for the Arduino Morse decoder is that it determines the Morse speed automatically by . '; else if (tijd > StreepDuur) teken = '-'; else if ((tijd > (StreepDuur + PuntDuur) / 1.9) && tijd <= StreepDuur) teken = '-'; else teken = '. But we need neural network driven one! I have an idea to upgrade this project: add a third potentiometer to control the duration of a dot/dash/pauses. ", "--. Added a pulldown resistor and capacitor to reduce bouncing. include // Arduino pin i/o class header Arduino - LCD Controlling LCD is a quite complicated task. Every operators style, or fist, has subtle variations in the timings of the dots, dashes, and the pauses between these elements, the letters, and the words. For more detailed information about the test results, please look at each example's comments This project is an Arduino program, that listen to the serial port (reception/emission) and outputs two things: It also send back what it received, prefixed with "Received: ". ", ".", "..", ".---", "-.-", ".-..", "--", "-. Soon I would be hearing messages by spies in exotic locations, possibly in an attic, wearing trench coats and fedoras tapping out their secret messages to their HQ, or more likely not. I started with D13 as it was already on the module. Buut some added some preprocessing, hardware to differentiate between dots and dashes. On that board, pins 7 & 8 aren't brought out but actually used to communicate with the module's flash. This is javascript only morse code listener. There is an LED on the audio module that lights when the output goes low (receive). I dont know that it matters, but dont know that it doesnt. VZ200 Glass RTTY (legacy article) Arduino Project Tips. Ian liked mini (Pi)QWERTY USB keyboard II.. AirCruiser has added a new log for DJI FPV - Battery Breakout Mod [3]: Breakout Board. 1 x LED to display the status of the Arduino. Hi Frank. Arduino-Morse-Code-Decoder Using a microphone module connected to an Arudio nano, recieved pulses of morse code are convereted to plain text and and displayed on a 20x4 LCD module. Directly across the River IJ, Amsterdam Noord boasts the best of contrasting worlds: vast green expanses and charming little villages plus some of the city's most cutting-edge architecture, exciting festivals, museums, gig venues, fantastic dining options and waterside hangouts with beautiful terraces. lcd.begin(LCD_COLS, LCD_ROWS); // Use when not using a backpack It was some time before I got any success with that, which brings me to an unexpected feature of the audio module. // For HD44780 library (with a backpack?) Morse code translator is the process of dot and dash to convert in English alfabates Here is 3 main fealdes 1 st one mode 2 nd one is input box for your text and 3 text box is for morse code output. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); https://github.com/garrysblog/Arduino-Morse-Code-Decoder, http://arduinolearning.com/code/ky038-microphone-module-and-arduino-example.php, Measuring audio frequency with anArduino, Morse Code Decoder using an Arduino Nano Garrys blog | Iz4fvw.net, Converting LifeChat headset for external output and mic with Zoom and MSTeams, Chroma-chime: A kit using the first commercially availablemicrocontroller, Making an iPad/tablet holder from abookend, Updating my 30 year old home madespeakers, Using an ESP32 to get my WordPress viewingstats, Queuing files to the DFPlayer mp3 playermodule, Circuit board damage due to leakycomponents, Converting a bamboo utensil holder into a toolholder, MP3 DFPlayer notes: clones, noise, speakers, wrong file plays and nolibrary, MP3 speech files for use in clockprojects.

I tried to burn this to a Wemos board ESP-WROOM-02 without thinking enough. The free CwGet morse decoder download for PC works on most current Windows operating systems. const byte LCD_COLS = 20; Prosigns are characters that have a value that is has a text equivalent that is more than one character. The visitor may later copy letter by letter morse code in the hope that something readable on the screen. The sketch includes funtions for word wrap and scrolling. It looks like there have been different standards used that has resulted in some Morse patterns set to different characters or prosigns, for example -.. This is an Arduino program that decodes Morse code from an I/O pin. 204 LCD display. '; long tijd = abs(millis() - starttijd); if (tijd > StreepDuur - StreepDuur / 40) { DecodeerKar(); //Serial.print(); } if (tijd > StreepDuur * 2) { DecodeerKar(); Print(" "); Serial.print(" "); }//else DecodeerKar(); //Serial.println(teken);}void DecodeerKar() { static String letters[] = { ".-", "-", "-.-. Lesson learned: sometimes software problems aren't fixed by powering down. In fact, trained operators can recognize each other because of this, much like we can often recognize who is speaking on the phone just by hearing their voice. If a backpack is used the contrast pot and backlight resistor are not needed. This is simply connected to digital pin 8 and the GND of the Arduino. Any Morse it hears is displayed as plain text on a display. After reading this forum post I decided to give the hd44780 library a go. const byte I2C_ADDR = 0x3F; // Hexadecimal address of the LCD unit The built-in LED on the Arduino can be used instead of this LED and resistor below. I like green best, but most YouTubers seem to prefer blue. The Audio module I have does not have any markings but it appears to be a KY-037. DIY Comparatron Helps Trace Tiny, Complex Objects. We wrote about a couple of Morse code algorithms back in 2014, the MorseDetector and the Magic Morse algorithm. The decoded CW is displayed as text or can generate a side tone. This site uses Akismet to reduce spam. The more dahs you send at the beginning the sooner it locks into solid copy. Can decode Morse code, takes left button as an input; Buzzer squeaks to indicate when the left button is pushed; Outputs decoded text to an LCD display; Right button is . 6.8 uF tantalum capacitor for low pass audio filter. We redesigned the PCB, which could be fit into a compact aluminum enclosure, and trimmed the code so as to fit the features of AVR mega 2560. In the future I would like to let visitors on a museum ship try to write some characters on the display (interactive museum). I use it to train my own Morse keying skills. [Rostislav Persion] wrote a simple Morse Code decoder to run on his Arduino and display the text on an LCD shield. Very nice wright up and build but Im getting an error Garry would you please take a look at it? We care about the privacy and personal data of our users. 1 x resistor to limit current to the LED above. For auto mode, simply set the function to Auto. Morse code is developed by Samuel F.B. execute decode.m (just type 'decode' in console) A file selector will pop up, choose audio file (wav/ogg) and wait for results. If you are using the Arduino IDE we can probably rule that out. */, // LCD without I2C using HD44780 library So the standard settings expect a very clean code, which I cannot enter, because I am also not familiar with morse. Thank you!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Arduino/LCD Display I have adjusted the timing a bit. DMR. The sketch adjusts itself to. There is one already on the microphone module I used. Local guy who I have done some rework for makes this thing. I also tried installing the library using Library Manager, selecting HDD44870 by Bill Perry Version 1.3.2 and that worked to. (like long short short short = Battery). The text on the display Morse decoder was surprisingly accurate. Connect the buzzer between GND and pin 8 of the Arduino and the Morse key (I use a tactile switch) between GND and pin 7. A Morse decoder built today is more likely to be used to decode machine-generated signals, for example, debugging information or telemetry. Originally I downloaded the library from GitHub https://github.com/duinoWitchery/hd44780 and placed it in my Arduino library folder. Neat project! hd44780_pinIO lcd(rs, en, d4, d5, d6, d7); Check this out: http://www.k4icy.com/cw_decoder.html, Nice. In this example is displayed.

I will, of course, refer to your name and work in my modified code. const int rs = 7, en = 12, d4 = 11, d5 = 10, d6 = 9, d7 = 8; It can be driven from the PC sound card provided that the audio level is sufficient. Currently version 1.8.13. . The decoder automatically corrects itself for your keying speed. It makes no difference whether variables are named in German or some other language. 2 buttons, breadboard and a lot of jumper wires, Can decode Morse code, takes left button as an input, Buzzer squeaks to indicate when the left button is pushed, All inputs are debounced (as they should be). Setting buzzer(8) to an output led to a shoving match that the flash lost. Did you make this project? 3D Printed Morse Paddle. I based the conversion on the PARIS, Number of dot lengths per second = 1000 / dot length in ms, Where: T is the unit time, or dot duration in milliseconds, W is the speed in wpm, Examples: 150ms = 8wpm, 100ms = 12wpm, 50ms = 24wpm, 20ms = 60wpm. const byte LCD_COLS = 20; Upload this code on your Arduino board and open your serial monitor window. SOS is fine here, because thats what most people know and most people would be able to send. Those mechanical decoders (much like the project described in the article) require pretty close speed control, in order for the receiver to sync with the transmitter and produce mostly-accurate output. When the program recognizes the correct word, a servo will release a lock and provide access to the cache container. Speed adjustment is set by a potentiometer to the sending speed of the morse or alternatively the unit can be set to automatic mode. I found 22uF worked but sometimes affected the first mark in a word resulting in the wrong character being displayed. */, /* When the bar is pressed, it forms a connection Arduino bootloader. A Morse code decoder built using. $14.71 + $3.40 shipping. A tag already exists with the provided branch name. May I use this code as the basis for a geocache? For those who do not have the I2C type liquid crystal display it should be easy to change this to use a standard 1602 style parallel interfaced LCD. If the sound from lautspeaker is to high, then regulate the 100 Ohm resistor, but keep MIN. sorry for late reply, I am not sure how to upload the entire code, check the connections between the Arduino and the LCD, they should be smthg like: A 100ohm resistor to vcc (5V), Resistor values could be changed to adjust the backlight and char light to your needs. Ik heb wel de timing een beetje aangepast. doctek has updated details to AccelStepper - The Missing Manual. Secondly, in the same time, on the LCD screen, it writes the letter it is encoding and prints the morse code on the second line. When I started working on the project I started with just a simple home made Morse key I made and it wasnt until after that that I swapped to the microphone. LiquidCrystal_I2C lcd(I2C_ADDR, 20, 4); // Set the LCD address to 0x27 for a 20 chars and 4 line display It uses Morse code to act like 2 way paging or textinghas a 3w transmitter built in and can plug into higher power stuff. The RH pin in the sensor is for relative humidity signal while the T pin is for the temperature signal. gaps between marks should be one dot length and dashes should be three dot lengths but thats not always what is being sent. By using our website and services, you expressly agree to the placement of our performance, functionality and advertising cookies. I started with an I2C backpack on the LCD but it was not able to handle faster Morse. This library and its examples were tested on 2016-06-11 with common Arduino boards. If so that opens up further questions and ideas for exploration in the future. Under ideal conditions, both LEDs should be flashing at the same time and both only when there is sound from the speaker being monitored. Let us know in the comments below. Hi Garry, thanks a lot. Are you able to post the entire code with your updates? The code is available in my Github repository https://github.com/garrysblog/Arduino-Morse-Code-Decoder. The reset pin has a pull up . Arduino Morse Decoder: This device reads hand keyed Morse code from a signal key (or an ordinary switch) and translates it to plain text and show the Morse code you're keying on an LCD. The circuit consists of an Arduino UNO and a piezo speaker. Each character (letter or numeral) is coded/represented by a unique sequence of dots and dashes. const byte rs = 7, en = 12, d4 = 11, d5 = 10, d6 = 9, d7 = 8; In this project, we will print out Morse Code of a sentence typed in Serial Monitor by flashing LED for each word and space between them. StreepDuur == the duration of a dashtijd == timeThe statement "if (tijd > StreepDuur - StreepDuur / 40): decodes a space between two letters.And "(tijd > StreepDuur * 2)" is for decoading a space between words.Som more explanation:PuntDuur == Duration of a dotstarttijd == Start time. (LogOut/ Some time ago I saw a YouTube video about a Morse Code decoder that was based on a micro controller. Just to rule out a couple of other things Ive tried recompiling and uploading using different methods. In an earlier era of Morse code decoders, one tough part was dealing with the idiosyncrasies of each sender. This Arduino based CW decoder was developed by Hjalmar, OZ1JHM. Info over arduino morse decoder. ", "--.-", ".-. Make a Morse Code Encoder w/ Arduino. Have you used Morse code in any of your projects before? Here we used Arduino UNO to translate a text to Morse code. The other difficulty these decoders faced was detecting the signal in low signal-to-noise ratio environments pulling the signal out of the noise. ", "-..", ". . It seemed like a good idea to support SOS and if I was going to do that I may as well cover as many prosigns as possible.
