  Arduino 101 "Infinity Mirror." The rotation angle of the Arduino 101 changes the lights in a Neopixel strip.
  This code uses the Adafruit Neopixel library. Library installation instructions here: https://learn.adafruit.com/adafruit-neopixel-uberguide/arduino-library-installation
  If using the desktop version of the Arduino IDE, make sure you have the latest Intel Curie Core installed. For more info, visit https://www.arduino.cc/en/Guide/Arduino101
