CircuitPlayground

Arduino sketch for Adafruit's Circuit Playground Classic (ATmega32U4)

Programmed with 4 animations:

1. Left switch side, left button - plays Happy Birthday

2. Left switch side, right button - lights up purple. In dim lighting, becomes brighter.
   To switch colors, press right button while holding any of the capacitive touch sensors. (It's a bit finicky: if it doesn't change right away, keep holding and pressing the button.)

3. Right switch side, left button - accelerometer animation

4. Right switch side, right button - lights react to sounds
