A couple of years ago, my friends adopted a dog for Christmas, and that inspired me to get a special gift : an automatic kibble dispenser . After months of ideas, I managed to make it happen. To make it work well, I created a circuit with a display and various menus, as well as a motor connected to some kind of auger to measure out food portions.

Automatic pet feeder (circuit) - Floppy Lab here you can find a description of the circuit that I designed for this automatic dispenser.

I hope you can find this usefull.
Probably I will do a YouTube video on it, follow me on Floppy Lab - YouTube to don't miss it.
