This schematic (plus a physical, non-coded ramp) will feed your dog one treat at a time.

My project builds a dog treat dispenser, one treat at a

time. It uses a remote control (even your normal TV remote if you want!) to dispense a single treat. It includes an optional LED to show when the treat is coming. I picked this because most dog feeding machines are to feed your dog an entire meal. This one simply gives out one treat at a time. It can be used as a training tool, because I bet your dog will sit in front of it for a long time waiting…s/he/they can practice stay! You can also get your dog away from you by giving out a treat. They will come running when they hear the beep once they know it means treats!

This is meant for the advanced user.
