Jim Campbell Windshield Wiper

An attempt to make a video screen out of one swinging strip of LEDs. The lights are mounted on a rigid vertical pendulum which is attached to a servo motor. The motor controls the angle of the pendulum, which is monitored by an Arduino which spits out color data to match. Thus, if a long-ish exposure camera is used, a full image appears on the wall. 

The piece is an homage to the artist Jim Campbell and his work using LEDs to explore the minimum amount of information needed to convey an image.

The Setup

The Effect

The original image is of a sunflower. The fourth image down is taken with a roughly one second exposure.
