This is a mini arcade where you can play Pong, a simplified version of the classic game Asteroids, and an etch-a-sketch. It also controls a strip of neopixels - you can set the red, green and blue values and turn it off and on. It also ran a program that displayed the mandelbrot set, but the Arduino got maxed out, so something had to be removed.
