The Reebok CheckLight is a sports activity impact indicator for athletes at risk of head injury, like football and hockey players. The lights at the back of the neck light up in reaction to severity and cumulative number of head impacts as sensed by an accelerometer and gyroscope. Check out the guide on the Adafruit Learning System for more closeup photos and a list of the parts on the board.
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.
