The GPIO extension gives you the flexibility to connect and control a whole host of electronic devices. Its layout and functionality is very similar, so you can use it as a drop-in replacement. GPIO extension is a replacement for the existing extension in Scratch 2. Scratch 3 Desktop for Raspbian comes with new extensions to allow you to control the GPIO pins and Sense HAT with Scratch code! Sudo apt-get install scratch3 What can I do with Scratch 3 and Raspberry Pi? Open a terminal window, and type in and run the following commands: sudo apt-get update How to install Scratch 3 using the terminal Open up the menu, click on Preferences > Recommended Software, and then select Scratch 3 and click on OK. How to install Scratch 3 using the Recommended Software app Once you’re running the latest version of Raspberry Pi OS, you can install Scratch 3 either using the Recommended Software application or apt on the terminal. If you’re already using Raspberry Pi OS, but you’re not sure your running the latest version, update your OS by following this tutorial:.If you’ve yet to upgrade to Raspbian Buster, we recommend installing a fresh version of Raspberry Pi OS onto your SD card instead of upgrading from your current version.You can only install Scratch 3 on Raspbian Buster and on newer Raspberry Pi OS versions. The Scratch team is working to reduce the memory requirements of Scratch 3, so we will hopefully see improvements to this soon. While you can run Scratch 3 on a Raspberry Pi 2, 3, 3B+, or a Raspberry 4 with 1GB RAM, performance on these models is reduced, and depending on what other software you run at the same time, Scratch 3 may fail to start due to lack of memory. Scratch 3 needs at least 1GB of RAM to run, and we recommend a Raspberry Pi 4 with at least 2GB RAM. In these six projects, your young people will learn how to use Scratch on a Raspberry Pi computer to control LEDs, buttons, and buzzers to make interactive games, displays, and instruments. If you think your kids would like to learn how to build physical projects they can program in Scratch, then take a look at our Physical computing with Scratch and Raspberry Pi path. Scratch and electronics with a Raspberry Pi computer Further Scratch: clones, my blocks, and boolean logic: On this path, young coders take advantage of all the tools in Scratch to code a range of different programs including simulations, games, and computer-generated art.More Scratch: broadcasts, decisions, and variables: On this path, kids can build on the skills they’ve learning in the Intro path to take their Scratch creations further as they code apps, games, and simulations.
