Light painting — the use of long photographic exposures and moving lights — is an oft-revisited maker project. This time ’round, we’re creating a high-fidelity light stick using CircuitPython on the Adafruit CLUE with a DotStar LED strip. Not the usual retro bitmap graphics seen in light painting, but super-smooth continuous-tone images.
CircuitPython, best known for its quick-to-develop, quick-to-iterate nature, can also deliver good performance if you know where to look. Aside from the build instructions and code, the guide offers a handful of tips there.
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.
