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.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
