/* 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).

   Connections

   ===========

   Connect SCL to analog 5

   Connect SDA to analog 4

   Connect VDD to 3.3-5V DC

   Connect GROUND to common ground
