You’ll have a fun time making this interesting pet feeder project that utilizes a real-time clock module, which allows users to time their pets’ feeding slots and also select the amount being given. When the set time is reached, the feeder will automatically drop the portioned food into the pet bowl.

The project directions provide written instructions, a video tutorial, code, and photo illustrations, so it’s very clear and straightforward to follow along with.

This Arduino project provides a clever way for cat owners to automatically program a cat feeder, in case you need to be out of town for a day or just during your pet’s dinner time. A helpful aspect about it is that it can be used for both wet and dry cat food (though we wouldn’t recommend using it for both simultaneously!).

In the project details, you’ll find that it contains a video tutorial, schematics and code, and thorough instructions on how to assemble this automatic cat feeder. Your feline friend will thank you!

If you’re looking for a hands-on Arduino project that will ultimately feed your pet, this dog feeder is also a cool way to incorporate 3D printing and some handiwork into your assembly.

This dog self-feeder can be programmed for automatic or timed dispensing of food or treats, so you can decide whether you want it to work in the moment to be pre-programmed. You’ll find helpful photo instructions and all necessary files and code included in the project details.

This fun and practical cat feeder uses both 3D printed parts (files included), an Arduino microcontroller, and a fairly complex construction, so it’s a good combination of various elements if you’re looking to be both hands-on and screen-on in putting together a pet feeder.

Designed to be ideal for dispensing cat treats in particular, it could also work for dog treats as well. The project includes a video tutorial, as well as links to the part list, code, and schematics. The creator also has a Patreon if you’re a fan of this style of project.

Bringing together the power of Arduino and Raspberry Pi, this button-operated feeder is a great treat dispenser for cats and dogs. You’ll save time during the day as it can be operated directly by your pet. (Don’t worry, it’s regulated in terms of how many treats they can self-serve!)

The project’s creator offers super detailed instructions plus all the needed schematics and code in the tutorial. Additionally, the creator also offers a livestream camera feed that shows how it operates in real time, which is really helpful for making sure that yours looks the same!

This creative self-service cat feeder is made with some items you’re likely to already have on hand (plus you get to re-use stuff, so it’s also a bit more eco friendly)! Using an empty chip can and plastic container, this cool feeder project lets your cat use its nose to push a button to dispense the food.

Containing helpful instructions and schematics and a good visual YouTube video, all the steps of this cat feeder are explained well, and a bonus is that the potentiometer allows you to adjust the amount of food distributed per feed.

If you’re looking for a challenge, but also a very creative project, look no further than this elaborate and well-designed Arduino project devised by computer science students. It will dispense your pets’ water and food, as well as monitoring how much they eat!

This project uses both Arduino and Raspberry Pi boards as well as some common household objects, so you’re likely to already have some of the elements on hand. Just note that the finished project isn’t completely automated, but will still streamline some of these tasks to make your life easier when it comes to giving your pet food and water.
