LED Lights on a trombone bell.
Well anyways, I'm planning on sticking a circle of little LED lights on the bell of my trombone. It would have two modes, one that lights up with noise, and the other just staying lit. I plan on using the circuit from https://www.instructables.com/id/LED-Music-Sync-Lamp/
but I need a microphone circuit and a switch added in to do the two modes i described. So could anyone sketch something up quickly? Thanks.
