/******************************************************************************
* Developed from
* VL6180X_demo.ino
* Example Sketch for VL6180x time of flight range finder.
* Casey Kuhns @ SparkFun Electronics
* 10/29/2014
* https://github.com/sparkfun/ToF_Range_Finder-VL6180_Library
*
* The VL6180x by ST micro is a time of flight range finder that
* uses pulsed IR light to determine distances from object at close
* range. The average range of a sensor is between 0-200mm
*
* Resources:
* This library uses the Arduino Wire.h to complete I2C transactions.
*
* Development environment specifics:
* IDE: Arduino 1.0.5
* Hardware Platform: Arduino Pro 3.3V/8MHz
* VL6180x Breakout Version: 1.0
*
*
* This code is beerware. If you see me (or any other SparkFun employee) at the
* local pub, and you've found our code helpful, please buy us a round!
*
* Distributed as-is; no warranty is given.
