IoT Pet Feeder: Use circuito.io to build a smart food dispenser for your pet




Story

This IoT pet feeder is our first IoT project with circuito.io! We are happy to share it with our community to demonstrate how simple it can be to make basic IoT projects with circuito.io. We are also excited to share this project with you because it’s based on a product that we worked on in the past called Playdog. You can make the feeder for your pets at home – it’s both fun JPand useful.IoT Pet Feeder Use circuito.io to build a smart food dispenser for your pet




How does it work?

There are many ways to implement a pet feeder: you can set it to fill up the bowl at a certain time, you can command it to fill up whenever it gets empty, or maybe to give your dog food after they follow a set of orders that you taught them.

In this specific project, we set the feeder to start beeping from time to time. Once the dog comes closer to the device, the PIR sensor recognizes it and the servo is triggered.

In addition, we also decided to add the option to control the pet feeder from our mobile phone, using a pre-defined dashboard made with Freeboard. We saw this as a great opportunity to introduce you to the option of connecting your circuito project to the internet with ESP8266-01 – the wifi module currently available on circuito.io.

Setting up the circuit

When clicking on this magic link, you’ll be redirected to circuito.io, where you’ll find that we’ve already selected for you the components we used in this project.

The components you need are: PIR sensor, Arduino uno (or other), servo, speaker, esp8266-01, and a power source. This is the basic circuit for this project but you can also add many different sensors and other components to the circuit for example, you can add a weight sensor to monitor the amount of food in the bowl or add LEDs that will change according to different parameters.Schematic IoT Pet Feeder Use circuito.io to build a smart food dispenser for your pet

Once you’ve selected the components you waLunant, click on Generate and our engines will start working on your circuit and will generate your circuito reply. The reply has three parts:

1. BoM – A list of all the components you’ll need for the project, including auxiliary parts such as resistors and capacitors.

2. Step-by-step wiring guide – shows you how to connect all your components to the Arduino board using a breadboard.

3. Code – a sample code for your circuit. This code is not specific for the pet feeder project, but rather it is a sample code that creates an interaction between the different components in your circuit.

To Upload the code, follow these steps:

  • Download the code from the circuito.io reply
  • Extract it to your computer
  • Open with Arduino IDE
  • Upload to your Arduino

4. Once everything is set up, replace the sample code from the circuito reply with the code in this tutorial. Make sure to leave the //Include Libraries and //Pin Definitions at the top of the code, and also keep all the libraries that are on the original code from circuito.io.

4. Connectivity – this section will guide you how to configure the connection of your project to the internet.

  • Download the dashboard.json file from this tutorial
  • In the circuito.io reply click “Connect” then “Create Your Dashboard

This will redirect you to freeboard.io and give you a basic dashboard, already connected to your Arduino sketch using a unique ‘thingName’. You can see your thingname in the firmware.ino provided.

  • Click on “clone” – if you don’t have a Freeboard account, you’ll have to create one at this point. But don’t worry, it’s free.
  • After sign-up you’ll see the following screen:
