+/*************************************************** 
+  This is a library for our Adafruit 16-channel PWM & Servo driver
+
+  Pick one up today in the adafruit shop!
+  ------> http://www.adafruit.com/products/815
+
+  These displays use I2C to communicate, 2 pins are required to  
+  interface. For Arduino UNOs, thats SCL -> Analog 5, SDA -> Analog 4
+
+  Adafruit invests time and resources providing this open source code, 
+  please support Adafruit and open-source hardware by purchasing 
+  products from Adafruit!
