/*
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.
