Did you know you can adorn your Raspberry Pi with HATs? Of course we’re not talking about hats like people put on their heads, but rather HATs: “hardware attached on top”. These are add-on circuit boards and accessories that add functionality to your Raspberry Pi.
You can, of course, use the Pi on its own, using programming environments like Scratch and Python to program it. You can connect individual components to the Pi’s general-purpose input/output (GPIO) pins and program them directly. However, there is a wealth of amazing and innovative add-on boards and accessories that allow you to do more with your Pi without having to wire them into place, and in neat form factors that sit directly on top of the Pi.
