i am pretty now to Arduino but i guess its just great! Now i have to realize a project with the following specs:
I need to make some RGB LEDs from LillyPad change their color depending on the sound which is recorded with a mic. Actually it's an equalizer only with colors.
What i wanted to know from you is the following:
1.) What hardware setup would fit these specs? 2.) Can you give me some hints on processing audio? Looks like i have to implemet a code that changes the color of the RGB depending on the discrete frequency of the audio signal. I have seen some FFT tutorials on the play ground. Are there any other approaches. DO you have some reading infos?
Thanks in advance!
