 *

 *  This is a library for the BNO055 orientation sensor

 *

 *  Designed specifically to work with the Adafruit BNO055 Breakout.

 *

 *  Pick one up today in the adafruit shop!

 *  ------> https://www.adafruit.com/product/2472

 *

 *  These sensors use I2C to communicate, 2 pins are required to interface.

 *

 *  Adafruit invests time and resources providing this open source code,

 *  please support Adafruit andopen-source hardware by purchasing products

 *  from Adafruit!
