    People make marvellous things for their pets with Raspberry Pi. Here’s a splendid hamster feeder tutorial from Christopher Barnatt of Explaining Computers, just perfect if you’re after a small project for this weekend.

    Raspberry Pi Zero Hamster Feeder

    Raspberry Pi servo-controlled pet feeder, using a Raspberry Pi Zero and two SG90 servo motors. This project builds on the servo control code and setup from m…

    All you need to build your hamster feeder is a Raspberry Pi Zero and peripherals, a couple of servos, some plasticard, sellotape and liquid polyadhesive, and some jumper wires. The video takes you very clearly through the entire set-up, from measurements to wiring details to Python code (which is available to download). As Christopher explains, this will allow you to feed your hamster controlled portions of food at suitable intervals, so that it doesn’t eat the lot in one go and, consequently, explode. What’s not to love?

  • How to control multiple servo motors with Raspberry Pi

    How to control multiple servo motors with Raspberry Pi

    Reading Time: 2 minutes

    In the latest Explaining Computers video, Christopher Barnatt explains how to use servo motors with Raspberry Pi. Using servos is a great introduction to the digital making side of computing; servos allow you to control the movement of all manner of project components with your Raspberry Pi and a motor controller attached to its GPIO pins.

    Raspberry Pi Servo Motor Control

    Control of SG90 servos in Python on a Raspberry Pi, including an explanation of PWM and how a servo differs from a motor. You can download the code from the video at: https://www.explainingcomputers.com/pi_servos_video.html The five-pack of SG90 servos used in this video was purchased on Amazon.co.uk here: https://www.amazon.co.uk/dp/B07H9VC698/ref=nosim?tag=explainin-21 with a similar product on Amazon.com here: https://amzn.to/2QHshx3 (affiliate links).

    Servos and your Raspberry Pi

    Christopher picked up his SG90 servo motors online, where you’ll find a variety of servo options. What type of servo you need depends on the project you want to create, so be sure to consider the weight and size of what you plan to move, and the speed at which you need to move it.

    As the motor controller connects via GPIO, you can even use the tiny £5 Raspberry Pi Zero to control your servo, which makes adding movement to your projects an option even when you’re under tight space constraints.
