API for the Grove LED. More...
UPM module for the Grove LED (or other similar light-emitting diodes). An LED is a small lightbulb that emits light in response to a small current. The longer wire of an LED connects to the positive seat (anode); the shorter wire connects to the negative seat (cathode). The flat side of the bulb corresponds to the cathode, while the rounded side corresponds to the anode.
