# Adafruit Unified BNO055 Driver (AHRS/Orientation) #
This driver is for the Adafruit BNO055 Breakout (http://www.adafruit.com/products/2472),
and is based on Adafruit's Unified Sensor Library (Adafruit_Sensor).
To work with the Arduino Zero, the BNO055's ADR pin must be high, and an "#error" must be removed from the .h file.
## What is the Adafruit Unified Sensor Library? ##
The Adafruit Unified Sensor Library ([Adafruit_Sensor](https://github.com/adafruit/Adafruit_Sensor)) provides a common interface and data type for any supported sensor. It defines some basic information about the sensor (sensor limits, etc.), and returns standard SI units of a specific type and scale for each supported sensor type.
It provides a simple abstraction layer between your application and the actual sensor HW, allowing you to drop in any comparable sensor with only one or two lines of code to change in your project (essentially the constructor since the functions to read sensor data and get information about the sensor are defined in the base Adafruit_Sensor class).
This is imporant useful for two reasons:
1.) You can use the data right away because it's already converted to SI units that you understand and can compare, rather than meaningless values like 0..1023.
2.) Because SI units are standardised in the sensor library, you can also do quick sanity checks when working with new sensors, or drop in any comparable sensor if you need better sensitivity or if a lower cost unit becomes available, etc.
Light sensors will always report units in lux, gyroscopes will always report units in rad/s, etc. ... freeing you up to focus on the data, rather than digging through the datasheet to understand what the sensor's raw numbers really mean.
## About this Driver ##

/* This driver uses the Adafruit unified sensor library (Adafruit_Sensor),
which provides a common 'type' for sensor data and some helper functions.
To use this driver you will also need to download the Adafruit_Sensor
library and include it in your libraries folder.
You should also assign a unique ID to this sensor for use with
the Adafruit Sensor API so that you can identify this particular
sensor in any data logs, etc. To assign a unique ID, simply
provide an appropriate value in the constructor below (12345
is used by default in this example).
