Does anybody know how I can make a Sound Activated LED Circuit?? I want to hook up some LED's and make them light up based on whats coming out of the computer. So if i'm playing techno music, the LED's would blink with the beat/music.
And also, what kind of circuit design programs are out there that i could possibly grab?
And one more thing, whats the difference between DPST and SPST switches??
