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