+/* How to run this sketch
+ *  - Connect Neopixel FeatherWing and Load sketch to Bluefruit52
+ *  - Connect using Bluefruit Connect LE app
+ *  - Send character using BLEUART
+ *  - Bluefruit will draw received character on Neopixel FeatherWing
+ *  
+ *  Note: due to the font is larger than 4x8 Neopixel Wing, you can
+ *  only see part of the characters (but you got the idea). 
+ *  Run the sketch with larger Neopixel Matrix for complete demo
