One of the coolest things about the Raspberry Pi is its GPIO pins. They’re just sitting there, waiting to be connected to all kinds of useful peripherals so your Pi can interact with the world around it.
Power an LED to signal the user. Place a button in the path of a circuit and detect when a user presses it. Attach sensors to read temperature and humidity, and plug other cards like the Sense HAT over top of the pins.
A few months ago, I got a set of 37 sensor modules on Amazon. I knew they wouldn’t directly interface with the Pi, but that it was entirely possible to do it, so I put them aside for later.
Well, I finally decided to pull one out, and thought the mini-joystick might offer some interesting… opportunities. 🙂

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.
