/*************************************************** 
  This is an example for our Adafruit 16-channel PWM & Servo driver.
  Servo test - this will drive 16 servos, one after the other.

  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, that's 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
