One of the main reasons for the Raspberry Pi's continued popularity is its 40-pin GPIO header, which enables users to connect electronic components and control them with a program. While other languages may be used, the code for physical computing projects is usually written in Python, something that's become a whole lot easier with the recent introduction of the GPIO Zero library. Before its arrival, connecting electronics required numerous lines of code just to get everything set up. GPIO Zero does all this boilerplate code for you, so you can focus on controlling the physical devices. As well as resulting in far fewer lines of code, it makes it a lot easier for newcomers to understand.

Phil King is a Raspberry Pi enthusiast and regular contributor to The MagPi magazine. Growing up in the 'golden era' of 8-bit computers in the 1980s, he leapt at the chance to write about them in magazines such as CRASH and ZZAP!64. When consoles took over the video games world, he missed the opportunity to program... until the Raspberry Pi came along. Phil is now an avid coder and electronics dabbler, who loves to work on projects with his six-year-old son.
