Arduino Morse (2015)

Arduino Morse Code Signaler


A CodeWars problem about binary morse code gave me the idea for trying to make an Arduino project that converts an ASCII message to binary morse code and then flash it on LEDs.

Languages / Libraries:

  • Python
  • C++ (Arduino)


  • Binary Morse Code
  • Serial communication
  • ASCII and other encodings

The CodeWars Puzzle

Binary Morse Code

Arduino Hardware



  • Working Arduino signaling device
  • Python script that converts text to binary morse code
  • Arduino device

Needed Improvements:

  • Refactor the Python code
  • Allow for signaling with ASCII bytes
  • More robust serial protocol
