LED Indicators

The development board features four LEDs that can be used to provide diagnostic information for the demo code that
comes with the board. At power-up, the LED array should flash twice in the following order: Blue, Green, Yellow, and
Red. This will indicate that the board is pre-programmed. Each LED is assigned to indicate the status of a certain
aspect of the IoT system, which can be found in the table below.
