Guy-Manuel de Homem-Christo (half of Daft Punk) helmet controlled via Arduino
STILL A WORK IN PROGRESS
Large chunks of code politely "borrowed" from https://github.com/adafruit/piccolo
Uses LedControl library (http://playground.arduino.cc/Main/LedControl) as well as ffft library (https://github.com/adafruit/piccolo/tree/master/ffft)
As I am currently focused on the hardware aspect of this project, once I move over to the software side I plan on using a Fast Hartley Transform algorithm to process audio frequencies more productively. Potential Arduino FHT Library (http://wiki.openmusiclabs.com/wiki/ArduinoFHT)
