If you want to write an app on the iPhone to control the GPIO pins (or really do anything on the Pi), check out my github repo: https://github.com/davidahouse/PiTalk
Nothing revolutionary, but I’m not sure that a lot of people know about the usbmuxd method for communicating with the iPhone (I know I didn’t). This method also works for the BeagleBone (and really any Linux computer).
And of course I used the Adafruit Raspberry Pi distribution. I think the future I would like to expand the app a bit to include some of the nice features of the Adafruit distribution.
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.
