I wanna have LED lights that'll react to sound when I play music and I'd like it if they were powered by the PC instead of having a separate power source for them. Does anybody here know how to make them?

I'm using a pair of 2.1 Edifier speakers, i'd like 1 or 2 LEDs on top of both left and right speakers, a strip of LED on the back of my 23 inch monitor, and a pulsating ring on my Sub.

Could someone list down what I would need and how to set it up? Google hasn't been all that helpful..

Try asking 0whitebox0

just cut it off your led wire rubber wire protection and your speaker's and stick it together after done sticking get a tape and tape it

What you need is basically a VU meter, same principle used for this:



In fact if you know basic electronics, building a DIY kit is simple, you can use your PC internal power supply for this.
