| Arduino - Processing Real Time Spectrum Analyzer | |
| This program is intended to do a FFT on incoming audio signal for a line-in input on PC | |
| The program is based on http://processing.org/learning/libraries/forwardfft.html | |
| The FFT results are sent to two arduinos via a string of 32 integers | |
| More information, including full parts list and videos of the final product can be seen on 12vtronix.com | |
