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
