Moisture-Sensor
The following sketch demonstrates a simple application of sensing
the moisture of the soil. You can know whether a plant needs water
or not by observing the results that the sensor outputs.
The circuit:
* Moisture-Sensor attached to pin 24 (J6 plug on Grove Base BoosterPack)
* one side pin (either one) to ground
* the other side pin to +VCC
* LED anode (long leg) attached to RED_LED
* LED cathode (short leg) attached to ground
* Note:
This example code is in the public domain.
