As described in week 4, I used the Modela to mill the board
A tip: If you are going to mill a board for a smaller chip (like 328P-Arduino) use a lower speed to mill,
the lower spped will make s clean milling.
At the first time I did this board I didn't clean it and the soldering wasn't so good.
And at the secoend time I followed Neil's advices how to make the board and this is the result:
To program the board I used Arduino examples and change the input and output legs according to the circuit
For doing so I followed this tutorial "how to program Attiny with arduino".
And this tutorial also: Embedded Programming - Arduino IDE.
This it the code I used:Code
