Design & Program The Network.

I'm going to design and build a network based on serial asynchronous communication. I'm making one bridge board and two nodes.
This is the first one and is the bridge board.

And now the node board. I milled two of these.

BRIDGEThe diference between the Node 1 and 2 is the number of offsets, in the firstone I used 2 ande in the secindone 4.

Programing

To programing each one of my boards I connect one by one to my ISP and then use the code from Fab Academy website. Code.But with the nodes I had one problem that with Tomas we find. this is.





The yellow line is the problem, I the energy was cut, so I cut the trace in the blue line and did a bridge with a cable.

Connecting and Testing

This are the boards connected to the network.



Next, you load the Arduino IDE, and click on the Serial Monitor button. On the Serial Monitor window you type 0, 1 or 2 and press enter after the node you typed. Then you should get your boards react. The node selected should blink twice and get a response on the serial monitor window.
