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:
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
