Arduino: Sound to Colour LEDs

My latest side project, Converting system sound to RGB LED mood light.


This set-up requires an Arduino, Windows (mac version is being considered) and RGB LED’s using ‘WS2801′ controller chips. Most commonly used with the Adalight system.

This uses two programs, a .net console program I have wrote that gets the values of the left and right peak sound levels from the system (meaning it works with every sound running on the OS) and sends it down a Serial port. Finally the Arduino IDE script that converts those values to the light settings.

My script gives two options, Black -> colour fading and Colour -> colour fading, Every colour is user defined. I am working on more options and currently making this system stable before release.
