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. 🙂
Each Friday is PiDay here at Adafruit! Be sure to check out our posts, tutorials and new Raspberry Pi related products. Adafruit has the largest and best selection of Raspberry Pi accessories and all the code & tutorials to get you up and running in no time!
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
