Anyone have a good RGB LED Music Circuit? Answered
I'm hoping to build a very large array of LEDs that will go along with the beat of whatever is playing on the PC. The goal is something like 200 RGB LEDs spread across the room (mainly in the separations of an IKEA Expedit). I have quite a few of these Expedits and wanted to create a circuit that would accomplish 2 things. First is a switch to control whether the LEDs cycle through colors, or go along with the music. If the switch is set for the music, the hope is to force the red channel to be a mid, blue as a low and green as a high pass. What would I need to accomplish this? Note: This is all going to be tied into an old 600w power supply I have laying around. It puts out 18A@12V on one rail and 15A@12V on the second rail, so power isnt an issue.
The controller I want to use to run the RGB LEDs under normal circumstances is the one described here: http://picprojects.org.uk/projects/bigmosfetrgb/index.htm ... Is there a way to add to this, bypassing the microcontroller and shifting to another method of controlling the LEDs when the switch is flipped?
I'm not looking for a complete guide, or even a full circuit ... a rough outline and part list would be appreciated though.
