Things used in this project

LED (generic)

Linear Regulator (7805)

Resistor 220 ohm

General Purpose Transistor NPN

Instead of using 1 led, you can use a led strip. If it's not working, you can try rotating the potentiometer on the microphone board.

I made two projects, one with a5v regulator, one connected directly to the battery.
