I have no idea which forum to put this in, but since it has to do with music, this is the one that I thought was closest to the subject. Anyways, if its the wrong forum, I'm sorry. Anyways here's my predicament. I got a pen a couple days ago that had a cool blue light you could turn on and off and that was really bright. Then I flickered it on and off while listening to music about 5 minutes ago and thought..hey wouldn't it be cool to have some lighting system that flashed along with the beat? I thought I read about something similar where people did the same thing with CCD's in their computers. I was wondering if anyone knew where I could find pre-built/tutorials on how to build one? Thanks for any help!
