littleBits Projects: Remote Pet Feeder

This is part of an on-going series of posts about littleBits projects. littleBits is available in the Adafruit store – Base Kit,Deluxe Kit, Synth Kit, Space Kit, Arduino Module, Arduino Starter Bundle, Sequencer Module, and Cloud Starter Bundle.

littleBits Remote Pet Feeder

When away, make sure your pet (fish, cat, dog) never goes hungry with this WiFi-activated feeder. You can either feed your pet remotely by pressing the button in Cloud Control, an app which allows you to connect to your littleBits circuit remotely, or you can set up an automated feeding schedule through IFTTT (If This Then That). IFTTT is a service that lets you connect to different web apps through simple conditional statements.

The circuit:

Remote Feeder Circuit

How it works:

Any time the feeder receives a signal through the cloudBit, the servo is activated. In our case, we attached a fish food container with a small hole drilled in its side to the servo. When the servo turns, a few pellets drop out of the container and into the bowl.

You can activate the servo remotely in a couple different ways. You can either use the littleBits button in Cloud Control to send a single pulse to the cloudBit, activating the servo. Or, you could use an IFTTT channel, like Date & Time to automate the feeding at times you set.

Date and Time IFTTT

The cloudBit gives you the power to design and build your own internet connected devices, enabling you to design products/projects that are specific and relevant to you. For more project ideas check out our Projects Page.


Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
