Light Paintbrush with Circuit Playground – Create beautiful, expressive light paintings using the Circuit Playground for long exposure photography:

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.
We have a rich history of light painting projects here at Adafruit, as well. Check out some of these excellent projects for incredible effects that involve persistence of vision images painted with light, and even thermal heat map painting.

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.

Before you get started, make sure you’ve been through the basic tutorials on using the Circuit Playground. You’ll need to have installed the Arduino IDE, added the Circuit Playground board to Arduino, and added the Circuit Playground library. This excellent guide, Introducing Circuit Playground and Circuit Playground lesson #0 will show you how to do all of that and get you going in no time!
