A somewhat silly project that uses an LPC11U24 to control the system, a Neopixel stick to provide light, and a sound FX board with a small speaker to make noise. I set the pins to inputs with pull-ups then connected 14 jumper wires to ground. Every time a wire was disconnected, the system changed its lighting pattern: color, blink timing, blink pattern (blink to white, black, random, or opposite the main color). The system also played a random audio clip. More details on http://embedded.fm/blog/2016/5/24/fistful-of-wires License: CC-A-NC
