/*
 *  Example of AS_BH1750 library usage.
 *  
 *  This example initalises the BH1750 object using the default
 *  adaptive auto-high-resolution mode and then makes 
 *  a light level reading about every second.
 *  (the sensitivity and resolution are automatically adapted 
 *  the current light conditions)
 *  
 *  Wiring:
 *  VCC-5v
 *  GND-GND
 *  SCL-SCL(analog pin 5)
 *  SDA-SDA(analog pin 4)
 *  ADD-NC or GND
