This is the lay out of my board. It contains: Two leds, three switches, one 5V generator, three resistors, one crystal, one batery, two pin headers of 2x3, one pin header of 2x2, one FTDI 6 pin header.
This is the schematic, it was a bit tricky to make it small with the three switches one between the other.
2- MILLING with the PCB with the MODELA small milling machine.
This is the resoult after milling and soldering all the components.
The LED throught hole at the back.
This are all the components connected and how does it look.
3- PROGRAMMING PART with Arduino software.
In order to program my board first I unpluged the batery and also the 5Vgenerator because when I plug it it was getting hot so I had to unsolder it.
I had to connect it with the USB Ispprogrammer and to the computer.
Before to program it I had to read the USBisp programmer in the GUIT BASH. And then I was ready to program it with Arduino software.
This is the final code I have used for my project with Arduino software.
Once the code was working I unsoldered the FTDI 6 pin header because I didn't need it anymore once i is program it.
3D modeling with Rhinoceros.
3D milling WITH the CNC, ShopBot machine.
This is the final resoult
LASER CUTTING wood and acrylic of 3mm. and sticker black paper.
I have ingraved the letters in the wood.
This is acrylic of 3mm. and sticker black paper laser cut it.
This is the front side.
Finally I have introduced the circuit into the box.
Bill of materials
Conclusions
I am very happy with the resoult of this project as I am
solving an existing problem so it is a useful product and the design is acceptable.
But I have to say that the electronics is still my uncomfort zone as I had many difficulties to
reach the final code. The help of Emma was always needed for me as if not I was always lost but at the end I understand everything I did. Also the limited time didn't help to really think in the design of the product and it could be improved.

Many thanks to EMMA PARESCHI:
I want to clarify that without the help and patience of my supervisor, EMMA PARESCHI, I couldn't have finish the course and project. She has always helped me when frustration and feeling lost. She always pushed me to the motivation and work more profesional and organized. MANY THANKS!
