Arduino Color Morse Transmitter

This is my first project made with an Arduino UNO. It is super-simple, and requires only few components:

  • 1x Arduino UNO board (indeed)
  • 3x 220 Ohm Resistors
  • 1x 3-colors LED diode
  • 1x Breadboard and few wires to connect everything

Code

The code is very simple: there is a single function that can be called in the loop, called morse; the function expects 4 parameters: the first, is the text to show in morse code; the other three parameters are the Red, Green and Blue component of the color (from 0 to 255).

Circuit

The image of the final circuit has been created using fritzing; the software is Open Source, and can be downloaded here: http://fritzing.org
