I’ve just spotted this new resource on the Raspberry Pi website’s resources section. It shows you how to get started with controlling the Raspberry Pi’s GPIO pins using visual programming language Node-RED. It’s a nice tutorial and helps you get your head round some of the intricacies of the language and how to configure it to work with the GPIO. Read it here. Shameless plug: If you’re after the components to do the tutorial, you can do worse than getting the £5 CamJam EduKit from The Pi Hut.
