+/**********************************************************************************
+ * This program monitors the power on state, kill state and battery voltage on
+ * Woodstream mouse trap using the Multitech mDot and UDK2 development system.
+ * The power on state is monitored on the PA_4(UDK2 Pin D10)and the kill state is
+ * monitored on the PA_5 (UDK2 Pin D13) Digital Input Pins.  The battery voltage
+ * is monitored on the PB_1 (UDK2 Pin A0) Analog Input.  The status of these pins
+ * are transferred from the mDot LoRa to the Conduit LoRa gateway.  The status is
+ * also shown on the USB Debug Terminal Window.
