For this week assignament: design and build a wired &/or wireless network connecting at least two processors. As I had no idea of how this worked, I decided to do the hello.bus.45 board with the asynchronous serial to first learn and then try to do my own networking boards.
BRIDGE 
NODE 
_NETWORKING AND COMMUNICATION
First download C and makefile.
You will need to modify the hello.bus.45.c code for each node that is being programmed by changing the line #define node_id '0'. Each node has to have a different number.
Run make -f hello.bus.45.make program-usbtiny in the terminal, for each node with its defined number. In my case its 0,1,2 as I have one bridge and two nodes.
Use the Arduino Serial Monitor to send and read the information being transmitted by typing the number of the node you want to flash.
