    Sound Activation?

    This seemly simple setup has me stumped. I want to use FB with a small mic for analog input to vary the voltage to my lights in proportion to sound (Bass mostly) How would I setup a mic for the input. I was thinking just to cut the mini-plug off the end of a computer mic, and just use it. But not sure how to wire it to the board pins. Any advice?

    Okay, this may be a dumb question. It's late & I'm old. How is the Brain going to vary the output voltage?
