Instantaneous volume & breathing pattern I didn’t like so I threw it out.

Instantaneous volume display - threshold setting mode for each of the 7 bands.  ROYGBIV = 1-7.  Bass is RED, Violet is Treble, and every color in between.

Overview
Geometric Lotus - Originally designed and built by Ian Keller for his senior design project.  Donated to the KOI Buners of Cincinnati, Ohio after Scorched Nuts 2011 (Ohio’s official Burning Man regional.)  This video is after it was reprogrammed from Ian’s senior thesis code (colors analogous to the BP logo) to the original “Full Rainbow” code.  Effectively, I am it’s caretaker.  The only improvements I’ve made to the hardware were some mounting arms on the back so we could wall mount it, and some hot glue to keep the wires secured to the Arduinos.

Background
Arduino Powered: 1x Arduino Due, 1x Arduino Duelminalove provided to replace Ian’s by a KOI Pound member.  The project has two brains because Ian uses the hardware PWM channels (6 each, 12 total) to drive two rings of common cathode RGB LEDs mounted on the back of the lotus structure.  Each arduino has slightly different code that starts the RGB fade in a different spot in the sequence, such that the flower pushes color from inner most LED ring to outermost.
