Blinking bi-color LED on music?
I'm looking for a simple circuit wich can blink multiple bi-color 2-pin LEDs(using both colors of course).
It needs to blink on the beat of music, using a mic as input.
I would also like the sensitivity to be adjustable.
And it would be fantastic if all this could run on 3 AA batteries(4.5V).
I've done some research but couldn't find anything like this, only circuits that blink a bi-color LED or flash a LED on music.
Unfortunately I haven't got enough skill to combine these into a working circuit.
