Morse Trainer
Difficulty
Signt & Sound
Summary
Listen to secret coded messages on the short-wave radio with this real time Morse code to text translator! 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. This project comes in two parts, with the filter on a separate PCB and the Arduino shield containing a buzzer and a push button for Morse sending practice. Of course, you could always attach your own key!
