Automatic Fish Feeder Remixed

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.

With slide for moisture mitigation

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.
