It features a robust smartphone companion app that allows you to control feeding portions down to 5g increments and you can program up to 15 meals a day, making it great for both cats and dogs of varying sizes.

I'm hoping that turning force and jamming aren't an issue for me.We chose the WOPET 6L Automatic Cat Feeder as our top pick for the best pet feeders due to its long list of features and sleek design that looks a lot like a top-shelf coffee grinder. Will post more when I finish up and test this thing out. If the speed is indeed an issue, I'm thinking that if you just set the initial delay to 8 hours and planned accordingly, it would work as it's supposed to even if it resets after one cycle. In application this would essentially just feed my food crazy cats every 3 seconds until they food coma'd next to the bowl. The servo was turning after the initial delay, then the arduino would reset and the initial delay would start over. If the slower speed isn't powerful enough to turn the crank, I may have a possible solution.

So I'm hoping that when's it all assembled, it will have enough power to turn the rubber fins, which seem to be incredibly sticky. One of the potential problems, though, is that the slower the servo the less torque it has as well. I slowed the speed of the servo down and haven't had any issues with it yet (servo.write(30)). I had issues with my Arduino board resetting from the high power draw to start the servo (same board and same servo as listed). Taking a cue from the 3D printed pet feeder 'ible, you could have the servo rotate a tiny bit backwards before going forwards to dispense the food. I had some thoughts already that could be fun to experiement with: About halfway through (bought all materials, have arduino programmed, waiting for glue to dry on crank).
