With all the various holidays coming up I thought I would do a nice decorative project. This makes LEDs light up with any kind of sound - it might make a cool halloween effect that makes LEDs flicker as people walk past your house or you could have it on your TV or something at christmas or of course anything else you could think of (if you have any ideas let me know)
as usual it is built and tested - it works beautifully and is quite sensitve however if you want to control the sensitivity change R4 to something like a 2K potentiometer or trim pot and adjust to suit.
for the microphone I used one I salvaged from and old phone similar to ( Mouser number 665-POM5238PR ) but I'm sure any kind of microphone will work.
