Light painting is an artistic photographic technique combining long exposure times with lights in motion. Traditionally these images have been hand-painted with a penlight…but more recently, affordable microcontrollers and addressable RGB LEDs have brought a new high-tech twist to the idea.
A few such projects have been featured on tech blogs, most notably the LightScythe by Gavin “The Mechatronics Guy,” which uses an Arduino and a two meter bar of LEDs. The resulting photos, with their intense colors and mid-air suspended images, have been super popular, and rightfully so.
Large, colorful images require a lot of memory…and that’s one area where we’ll need more memory than we can store our Arduino. We had a hunch that the Raspberry Pi could make this process easier. But even we weren’t prepared for what a cakewalk it would be…
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.
