There is a project I got in my head to make something so I don't always have to feed my dog. But to make this, I need to learn about motors. So I got to know a bit about motors and what I wanted the motors to do is the following:
For the part where the dog's grain drops down, I thought a stepper motor would be the best. But how do I make the things that stop the grain from falling down the tube? I have no experience with this and would like to have some help.
The other part is the dog's water, how do I make that drop down or get in his bowl, I have no idea on how to do this. I thought of something like a water cooling with a desktop pc, but is that the best thing to do?
