I finished the electronic circuit. Well, at least in a sort of alpha-version, that does what I want it to do. I also worked a lot on the board and get it as small as I have to. It is my first project of this kind, and I am pretty sure, there are better ways to do it, but that is, what I have come up to.
The current PCB for download as Fritzing Layout (not finished) is apx. 150 KB
and the Arduino Sketch for a start to download (even less finished) is less than 20 KB.
Both downloads see down below in the "Documents" section.
Did This Help You? If so, I would greatly appreciate it if you commented below and shared on Facebook
