Inspired by Loek Vellkoop, I recently chopped up a scrap kid’s bike to see all the materials I could reuse from it. One of the elements that really struck me was the wheel rim after I had taken all the spokes out.
Solid, made from steel, and perforated with precisely spaced holes, I thought it would be cool to light it up with LEDs as an accent lamp, or just something cool to trip out on. So, that’s what I did, and I’m proud to say that I whipped it together in an afternoon while my family was out shopping.
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, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, 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.
