realtime arduino spectrum analyzer Real time spectrum analyzer powered by Arduino

I like where this is heading: Paul Bishop has created an Arduino-based real-time spectrum analyzer, that displays it’s output on a TV. He used an FFT library by Arduino forum user deif to convert an audio input into frequency data, and the TV out library to display the results. I’ve been mucking around with shoehorning an assembler-based library onto the platform, however his version looks like it might be nicer to work with.

First person to build an Arduino-powered color organ wins! Check out his blog post for the source code and a video demonstration. [via Arduino blog]
