Some time back, I joked that the Raspberry Pi’s GPIO port really stood for Game Port IO… So to make that joke come true, I present a way of interfacing the NES Joysticks to the Raspberry Pi.
First you need the joystick/controller unit, and a quick trip to the Plymouth Market where I’d had a tip that there was a stall selling retro gaming gear and I returned with a pair of them for under a tenner. Bargain!
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.
