Just saw your post on boingboing about wrapping LEDs around your handlebar. I thought you might be interested in some of the work that I’ve been doing with LEDs and bicycles.
I wrapped my bicycle frame with LEDs for the Bike Parties popular around here in the Bay Area and recently published the source code (runs on an Arduino) for the algorithm that blinks them to the music along with uploading a video of their operation today. Funny timing as I gave a talk at Noisebridge last night about these projects and met up with a few others that are working on this stuff for Burning Man during Circuit Hacking Monday at Noisebridge. There’s a nice community growing around here.
Anyway the source code is posted at Github and a demo is in the video above.
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.
