led array
I'm so fascinated for the light effects, that's why I decided to make the LED array.
Before you start, I suggest you to look at these websites that kindly our teachers have shared with us, about
Charlieplexing and its theory.
After cutting the board with our Modela, I started to solder the component... and wow! there are a lot! it was a great challenge but I'm happy to have succeeded at the first attempt.

[x1 ATtiny44, x1 Resistor 10k, x1 Capacitor 1uf, x1 Regulator (IC2)5V, x5 Resistor 449ohm, x20 Resistor 0ohm, x20 LED]
When I connected the board to the FabISP, I compiled it with Neil's C code:
make -f hello.array.44.make program USBTiny
[C file - Makefile]
Watch my video to see how is this effect!

step motor - unipolar
I tried to make also a Step motor (here you can find a short but effective explanation about the world's motor) in order to see if it was strong enought for my final project (pinball or interactive pinball). Once milled and welded I was almost ready to see my motor moving. [board - traces - outline]

Sincerely it was a bit hard to connect the wires in the right way, because my board Step motor has only 5 pins and the board 6; After comparing Neil's motor with mine, I figured out how were the right connections:
..and here below you can see the movement!

lcd
I worked also with LCD (mine has this data sheet) directly with my Arduino.
