LED Spectrum Analyzer


This looks like a fun project to make. I don’t think making an Arduino port would be too hard either. You can download the code on the website if you want to try and make your own LED Spectrum Analyzer.

This is a simple spectrum analyzer on an 8×8 red/green LED Matrix. An Atmel ATMEGA32 microcontroller talks to a laptop running an mp3 player called XMMS on Linux. XMMS does a fast-fourier transform and sends the computed values to the microcontroller.
