Real simply, i used a microphone circuit for input, amplified it, ran it threw a potentiometer so i could control how senstive it was to ambient noise then split it into 3 band pass filters to tune out other frequencies then used that as an input for my arduino. A simple conditional based on that input controlled 6 digital out pins with each pin connected to a single input on 2 separate red, green, blue LED’s. So since each LED has 3 inputs, thats 6 pins to control 4 RGB LED’s.
I ran everything off of 2 nine volt batteries, one as +9v and the other as -9v. I included a simple power schematic. I used the arduino for all my grounds.
This is your overall shopping list. In each section i will let you know what parts you need from this list but don't get confused and think you need more parts. This is the complete listing of all parts needed to make this project.
NOTE: if you make changes to the parts list, i'll try to detail how this affects the overall process in each section but no promises on the end result if you do
1x arduino (of any type, the code is pretty light stuff)
8x 1k ohm resistors
5x 10k ohm
7x 560 ohm
3x 150 ohm
4x RGB LED’s
8x 0.1 uF ceramic capacitors (this saves you trouble later since you don't have to worry about anodes and cathodes on these types of capacitors)
2x LM358N op amps
1x LM386 Audio Amp
1x microphone sensor
2x 9v batteries with battery holders
approx 2 miles of wire (just kidding but it seemed like a lot)
some kicking music to show off with
