Arduino Uno to LED Matrix and Microphone Amplifier

For my Arduino project I am trying to build an audio spectrum. Adafruit’s website has a kit describing how to build the audio spectrum - Overview | Adafruit Microphone Amplifier Breakout | Adafruit Learning System

My only problem is that instead of buying an adjustable gain microphone, I bought an auto gain microphone.

The difference between the two microphones is that the auto mic has 2 more outputs than the adjustable mic. I was wondering where these 2 extra outputs on my mic should connect to my arduino uno.

Let me know if you need any further information from me; I’ll be hawking this thread all day.

The mic mic defaults to maximum gain.

So there is no need to connect any other pins, unless you find the input is too high.

In which case connect the gain control to either Vdd or GND as this will give less gain
