An oldie-but-goodie, we were recently reminded of John Keefe’s Temperature Texter – recent like after a multi-month hiatus it recently kicked back on again and was tweeting temperature, humidity, and battery data on Twitter. You may be inspired by this to create your own FONA-based Arduino texting project – let us know if you do!
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.
