How would I make LEDs light up based on signal from a guitar pickup so they light up with my strumming? Answered

I ordered some 3mm 5000mcd leds (i hope they are bright enough I have no clue) and have my resistor values/ wiring diagram ready I just am trying to figure out how to make them flash like that. I'd like to have a 3 way toggle so there is

off - sound activated - steady on

this is a video with someone who has something like I'm thinking.


any help?


You mean like a twinkler.
to be honest ive been trying to figure this out as well.
I have instructions on how to install one but there is no instructions on how to build one, As far as I know its due to Jeonjoe (http://www.youtube.com/watch?v=8v9u0q2n650&feature=related) Trying to get a copyright on the design.

this circuit will drive the leds so that they will change based n volume of the music.... i have been meaning to build one of these myself.

Based on what I see there he just has color changing Leds. I'm talking about leds that flash when I strum and only when I strum. so they have to get signal from the guitar pickup somehow. Check out the video link I put in there. See how they flash as he plays. in conjunction with what he plays. Thats what I'm talking about.
