A couple of Adafruit customers decided to make costumes for their children that would stop traffic. Abrennr and amerasu both crafted traffic light costumes using NeoPixels and shared photos of their work (and their in progress sketches) in the forums. Abrennr used three NeoPixel rings and “used a different pin on the Flora for each NeoPixel ring, and just turned them all off and on as needed so that only one ring is ever lit at one time. Works great with my 3.3v battery pack!” You can see them in action in the below video:
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.
