circuit and board

I made boards of bus-network.

the firm was written like this.

I checked with in arduinoIDE. The work was mostly good. bridge and node2 was OK. but node1 had no response.

debug

I changed the cord which I used in week7 for tiny45 and checked of TXRX. It don't seem to be able to read the input from a keyboard.
