Simple music visualiser with Arduino


This is done during my brief fling with Arduino, before realizing that for the actual project that I wanted to do, requires more additional purchases than I’m comfortable right now (e.g. soldering station, servo motors, hydraulics from lego kits, etc)

Anyway, this visualizer is actually written in Processing, which first performs FFT on the audio track, obtain the frequencies, and then invokes Arduino library to write to the LED matrix.

You can get the codes here:
