Elecia White / Mbed 2 deprecated FistfulOfWires

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

Elecia 0:21fea82c85fc 2 Fist full of wires!
Elecia 1:0a051df78be2 3 The intention here is to make a ball of wires that someone can reach in and
Elecia 1:0a051df78be2 4 grab, changing the behavior of the system.
Elecia 1:0a051df78be2 5
Elecia 0:21fea82c85fc 6 So we read in the free IO lines, build up a variable.
Elecia 0:21fea82c85fc 7 If it has changed,
Elecia 0:21fea82c85fc 8 do the change actions:
Elecia 0:21fea82c85fc 9 make a bzzzzt sound
Elecia 0:21fea82c85fc 10 turn off all of the LEDs for a brief instant
Elecia 1:0a051df78be2 11
Elecia 0:21fea82c85fc 12 Use the created variable to choose the neopixel pattern
Elecia 0:21fea82c85fc 13 and the sound pattern to output to the audio (intermittent beeps)
Elecia 0:21fea82c85fc 14
Elecia 1:0a051df78be2 15
Elecia 0:21fea82c85fc 16 This program depends on neopixel library.
