automatic feed dispenser for cats and pets

Update thicker version:

At the request of a user, I sent a thicker version (2mm) of the shell.
check thicker version zip file, as the shell is thicker you should also print the new ramp and the bowl to adapt to this thickness

For now I have not made an assembly or connection manual but it is quite intuitive if you have a little skill in electronics or some experience with Arduino, they are basic connections.

The code is commented and indicates which pins the connections go on, the comments are in Spanish, which is the language in which I made it.

Let me know if you have any questions.

Greetings

I include Arduino code for local version: Check zip file TopCatV3
