highroads 0:47f8714fe967 2 * Developed from
highroads 0:47f8714fe967 3 * VL6180X_demo.ino
highroads 0:47f8714fe967 4 * Example Sketch for VL6180x time of flight range finder.

highroads 0:47f8714fe967 8 *
highroads 0:47f8714fe967 9 * The VL6180x by ST micro is a time of flight range finder that
highroads 0:47f8714fe967 10 * uses pulsed IR light to determine distances from object at close
highroads 0:47f8714fe967 11 * range. The average range of a sensor is between 0-200mm
highroads 0:47f8714fe967 12 *
highroads 0:47f8714fe967 13 * Resources:
highroads 0:47f8714fe967 14 * This library uses the Arduino Wire.h to complete I2C transactions.
highroads 0:47f8714fe967 15 *
highroads 0:47f8714fe967 16 * Development environment specifics:
highroads 0:47f8714fe967 17 * IDE: Arduino 1.0.5
highroads 0:47f8714fe967 18 * Hardware Platform: Arduino Pro 3.3V/8MHz
highroads 0:47f8714fe967 19 * VL6180x Breakout Version: 1.0
