Arduino Fish Feeder
Arduino Fish Feeder

Do you have a fish at home? Are you like me, and you occasionally forget to feed your water loving pet? If so, this project is perfect for you. Its Simple, Cheap, and fun to make!

This project is great for students who leave ealy and may not have time to feed fish in the morning

Please vote for this project in the DIY University contest and the Age of aquariums contest

This is an really cool arduino project, that uses just two electronic parts. The arduino sketch is set up to feed the fish every 12 hours, but you can change it to whatever number you like. After building, all you need to do, is to clip your device onto your aquarium and forget about it! Thats all you do!

Lets start building!

Note: I started a YouTube channel to document my projects better, subscribe for more projects!

Step 1: You will need...

Arduino Fish Feeder

For this project you will need

SUPPLIES

  • Arduino
  • Servo (any kind)
  • Binder Clips
  • An empty shampoo bottle
  • Fish Food
  • Jumper Wires
  • Empty food takeout container (Clean or unused)

    TOOLS

  • Drill
  • Hot Glue Gun
  • Computer (to code)

    Step 2: Shampoo Bottle

    Arduino Fish Feeder

    Using a empty shampoo bottle and your drill, drill a small hole on both sides of the shampoo bottle.

    This is where the food will fall out, so you should test if food falls out by filling it up, and rotating it while holding it horizontally

    DONT DRILL TOO BIG OF A HOLE!

    Your fish will end up fat!

    Drill a hole small enough so only 1-5 pellets fall out, depending on the size or number of fish you have

    Step 3: Wiring and Programing!

    Wire the ardunio according to the above picture.

    Using jumper wires, follow this pattern

    Connect Yellow or data to PIN 9

    Connect Black to GND
    Connect Red to +5V


    Next use the code I have provided to upload to your arduino

    Note: I'm not the best Programmer........ I'm still learning, If you see anything I can improve Please Tell Me!

    Step 4: Prepare Case

    First Cut a square just big enough to squish your servo through, It should be very tight!

    next get your hot glue gun and glue both the binder clips to the back of your case.

    Try to line them up as best as you can, They will clip to the back of your aquarium

    Next take some hot glue and glue a servo horn to the bottom of your shampoo bottle. Put the servo horn back onto the servo and go to the next step

    Step 5: Your Done!

    Simply fit all the electronics into the case, and wedge the servo in last. Now clip your automatic fish feeder to any aquarium and your done!.

    Have fun and now you don't need to worry about feeding your fish!
