Saw this bit of news about a blinky wristband that saved a company from bankruptcy on the Beeb this morning. I thought you might be interested if you’d not come across them before – they’re about a year old but not being a Coldplay fan, I’d never heard of them before today.
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.
