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.
