There are many great beginner projects out there which use the Pi’s GPIO (general-purpose input/output) pins. It’s great for coding too, since the Raspbian operating system comes with Python built-in. There is even a version of Minecraft for the Pi which can help you learn both beginner electronics and Python!
While this is great for people with some coding experience, what if you wanted to teach someone how to use the Pi’s GPIO pins without having to learn a programming language?
