Listens to a mic attached to an Adafruit Flora (a small Arduino) and creates mouth movements on an 8x8 grid of Neopixels. Optional pop detection for a smile :)
Hello, I have been trying to get your code to work with my Arduino Mega and have run into some issues, but your use of analogReference(EXTERNAL); is what confuses me the most. What have you connected to? The microphone seems to not work when it is used without a connection.
