This weeks assignment was to build a wired or wireless network with at least two nodes. I built the Hello serial bus. I downloaded the files from Neils page and milled the "bridge" and "node" boards on the modella. I then stuffed all three boards. To program the boards I had to change the "node id" in the "hello.bus.45.c" file. I made the node id 0 and flashed the bridge board. I then change the id to 1 and flashed the first node board. Changed it again to 2 and flashed the second node. With the programming done I went to the Arduino IDE and opened the serial monitor. I then typed "0 enter" . All the nodes flashed and then the bridge board flashed again. When I entered a 1 or a 2 all nodes would flash the the corresponding node flashed again.
