|
|
*
|
|
* The Grove light sensor detects the intensity of the ambient light.
|
|
* As the light intensity of the environment increases, the resistance
|
|
* of the sensor decreases. This means the raw value from the
|
|
* analog pin is larger in bright light and smaller in the dark.
|
|
* An approximate lux value can also be returned.
