If you take a look at the numerous pet feeders on Hackster, you’ll find most use a cereal dispenser, which is the approach I’ve taken. There are other implementations where people have crafted their own dispensing system, but who can argue for $20 on Amazon. And it comes with two dispensers, so you can make one for each pet, or have a backup when you explode the first one.
My initial plan was to attach a motor hub to the dispenser handle and attach a motor to the hub. As I started working with the handle, I noticed it slides right out, and has a not that let me use a standard motor coupler instead. So I cut off the silver handle and did just that.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
