I’m still plugging away at RPi Oscilloscope benchmarking GPIO using Java Embedded in my spare time (stuck on getting NIO to work), but for now I need a break, so I’ll go back to another cool use of GPIO using Java SE Embedded and a Raspberry Pi. Here are all the parts I just got for about $30.
I bought everything from RadioShack (except for the RPi), so you can do the same at home….
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.
