NEW GUIDE: John Park’s Light Paintbrush with Circuit Playground @adafruit @johnedgarpark
Paint with light using the Circuit Playground Light Paintbrush. Tilt the brush to change colors using the on-board accelerometer. This new guide will get you started in long exposure photography light painting.
Streaks of colorful light, suspended in midair — ever since people began to capture images on film we have had a fascination with light painting and light drawing. By simply moving a light source in front of an open shutter, motion over time could be captured on camera.
A Circuit Playground and a camera or smartphone capable of taking long exposure photos is enough to get started. By using the on-board accelerometer, you’ll be able to change colors by rotating the Circuit Playground. As an added touch, you can use a potentiometer to easily adjust the brightness of the NeoPixels.
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.
