Making the boards

I made one bridge and two nodes to try serial bus.
I added one more LED to each board so that I can check whether it's powered on or not.



To make the boards fast, I milled 3 boards all at once by setting x-axis differently when I make the milling files in fab module. I measured the size of the board and added 5mm gap.




By using USBtiny, I programmed the board with Neil's c code and make file.
In terminal application, I accessed to the directory where I downloaded the files and programmed it by typing in sudo make -f hello.bus.45.make program-usbtiny.

Then, I opend Arduino IDE to use serial monitor.

This is how it works.
