/*

  Example of BH1750 library usage.

  This example initialises the BH1750 object using the high resolution
  one-time mode and then makes a light level reading every second.

  The BH1750 component starts up in default mode when it next powers up.
  The BH1750 library automatically reconfigures the one-time mode in
  preparation for the next measurement.
