So the concept here is pretty simple. I wanted to mount a microphone on a stick with an LED and design a circuit that would react to a large amount of noise on the microphone input (blowing) to turn off the LED.
This could easily be accomplished with a micro controller, but I thought it’d be more thrifty and challenging to do it with analog components.
