Automatic Fish Feeder Remixed

cults3d

I took the automatic fish feeder that pefozzy created (thank you!) and tweaked it a little to fit the components I had on hand. Specifically a NANO arduino and a 9g micro servo (SG90). I also added a cap for the food bowl. The design is still a work in progress and has yet to be fully tested with the 3mm hole for portion size for 1 beta. I hope to do this soon. My daughter has a beta that is close to her heart that I'd like kept alive while we go away for vacation, and hopefully this will do the trick. https://youtu.be/qMpVXPntwms With slide for moisture mitigationhttps://youtu.be/DxEfcEwWTCU Materials: - Nano Arduino (elegoo in my case) - 9g servo & servo horn - misc screws After some insight from the original designer on moisture potentially being a problem with the betta food clogging the hole. To help solve this problem I've added a raised platform and food slide off at an angle for the delivery. Hopefully with the offset from the feeding opening I won't see the food affected by the moisture as much. Real fish testing still to be done. **Update positioned slide over open water of the tank for food delivery for a week, the food didn't absorb any water in the hopper. Seems to be a success so far. The arduino program for the nano is included in the files. The .ino file.
