Arduino realtime FFT

Thanks to user "deif" at the arduino forum, who converted an FFT algorithm for Arduino and also made it work with 8-bit integers, even I could make a realtime FFT display :)

Link to deif's FFT: http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1286718155

Notes: This is just a test, and the breadboard circuit shown is not primarily for FFT, I just threw it in there for fun :) Only using a simple two-transistor preamp for the electret mic also.

The date in the video is wrong, its made nov 23, 2010.

The song is "The Expert" by Yello from the album "Touch Yello".

Oh and apologies for the bad quality.
