Light Drive has it all.. stop motion, light painting, Arduino and some Tron soundtrack action.
The video is stop motion, so every frame is an individually shot photograph. Each photograph is a long exposure photo, with exposures reaching up to 20 seconds in some cases. The lights are controlled using Arduino controlled via bluetooth to drive a stepper motor. The stepper motor controls the movements of the lights remotely from Processing. The light sources include cold cathode case lights, EL wire, lasers and more.
