+ * UPM module for Grove LED (or other similar light-emitting diode).
+ * An LED is a small lightbulb that will emit light (turn on) in 
+ * response to a small curent.  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.
