  5  //    Sketch for "DiscoBandCamp" by Amelia T, 2019
  6  //    See Adafruit guide & XYmap.h for pixel map for more information
  7  //    Use Adafruit Gemma M0: 60 pixels to D0, 60 pixels to D1, & button to D2 & GND
  8  //
  9  //    This sketch shows mapping pixels on an irregular matrix and provides 
 10  //    various examples from RGB Shades Demo Code & the FastLED demo library.
 11  //    Can easily incorporate other examples or create your own!
 12  //    
 13  //    To use:
 14  //    Press the button to cycle through available effects shown on the functions list
 15  //    Press and hold the button (>one second) to cycle through five brightness levels
 16  //
