I created the hello bridge board to communicate between the bridge and
the nodes via serial. I created two nodes and a bridge board.
The programming of the boards went smoothly. I gave the bridge
board a node ID of 0, and the other nodes a node ID of 1 and 2.
For some reason, I couldn't power the bridge board with the USB
cable. I used a breadboard and external power supply instead.
I also didn't have a cable with 2x2 connectors, so I used a
breadboard to make the connections between Tx and Rx instead.
I used an Arduino board's serial port as
my computer output. I was able to get the LEDs on the bridge and
node board to blink. However, I coudldn't control the board with
the desired nodeID to blink. I did a loop back test between
teh Rx and Tx lines of the Arduino and found the following (even though
I was only outputting the value 1). I tried troubleshooting by
writing the data as "0x01" and flushing the buffer with no luck still.
I didn't have enough time to troubleshoot it so will have to come back to it.
