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.
