Aim of the week:
Redesign the echo hello-world board pcb (adding at least a button and LED).
Drawing
By using Eagle I draw the board.
The first step was downloading and using
SparkFun,
Adafruit and the
Fab libraries.
Firstly I added all the components and than I connetted them with the Wire and Junction commands.
From the original board I added one led, one button and a 10k trimmer.
After, I check the Electrical Rules and I moved to the Board Layout.
Milling & Soldering
Board milling was made with the Roland MDX-40a with the same process of the fourth week.
In the next image you can see all the components I've used.
The only 10k trimmer I found was not smd, so I've to solder it in a creative way! Here you can see what knob I choose to resolve that problem!
Here source files.
Flashing
After I soldered the components and checked every trail, I connected the board to the pc through the
Gianfranco's FabISP.
"avrdude done.
Thank you."
