If you’re stuck in the virtual world like [Kevin Flynn] you can still make sure your pup is rewarded for good behavior. Just follow [Jwarp’s] design for this Internet connect dog treat dispenser.
We were actually a bit surprised by the demo video. It shows that the compact unit is more than capable of reliably dispensing one treat at a time. It started as a wood prototype which allowed him to tweak how the servo motors worked before laying out all of the 3D parts in Sketch Up. Two motors cooperate to get the job done. The first allows one treat to exit that shoot coming from the center of the hopper. The other stirs the remaining inventory to both position the next treat and loosen any jams.
The base of the hopper serves as an enclosure of the Arduino UNO and an Ethernet Shield. A simple website is polled continuously. When it is found to contain the dispense command the hardware goes into action. The link above leads to the build photos, but there’s a bit of background info included in the Reddit thread.
This will go nicely with that automatic feeder you’ve been meaning to tackle.
