Week 14:

For this week, this assignment is to build wired/wireless network connecting at least two nodes.
i went for the serial bus board.
First of all i designed the circuit boards 1 bridge and two nodes (You will find the files below).

Second step is to mill all the boards.

Next step is to solder all the components to the circuits Tiny45, Capacitor and resistor, FTDI Headers, ISP Headers, Connection Headers, etc..).


Now! it's time for programming, and it's time for writing C not Arduino this time.
for each node i modified the code because each node needs to have a different node ID number.i changed the line " #define node_id '0' " for each node with its number.
after running sudo make for the C file, we're going to switch to Arduino IDE to test if the circuits are working or not?!
i plugged them all and open the serial monitor and when i entered the node's number they all flashed once and the node i called flashed one more time.
