![]() ![]() Note an audible 'beep' is optional, I drive this with a simple 555 oscillator from digital pin 8. We take the array of morse codes and break each one down into a dot and dash set, which we then individually send the LED to show the message in morse, with a dash lighting up for much longer than a dot. arduinomorsedecoder Tap in morse and show the letters on an lcd See below wiring diagram. Getting the sound detection working is probably a nice-to-have, so do that last if you have time. Then you can test out any Morse libraries you might download and get the LCD working. ![]() has a built-in controller for CWID and tone decoder/encoder, LCD display and 30. Am I understanding you correctly MorganS March 27, 2017, 5:48pm 4 Yes, just hook up the button directly to the Arduino. findLetter just looks up each letter and pushes the morse code. A mixer combines the IF signal with the frequency the Arduino commands. The overall idea is to break down the entry into its character components and find the relevant morse code for each (which is what convert_to_morse does). Any Morse it hears is displayed as plain text on a display. This is the other side of the encoder/decoder. Goal In designing the decoder I wanted to achieve: The decoder to use a microphone as the input. Plug in a Morse to the CWKEY socket to decode your own code and see the CW decoded into. ![]()
