No LEDs Required For Servo-Controlled Larson Scanner

It’s pretty easy to get one LED is a strip to light up sequentially, and have it bounce back and forth. Turning that simple animation into a real Larson scanner, with smooth transitions and controlled fade-out, is another thing entirely. The video shows a demo of servo support, with an eight-channel electromechanical Larson scanner. Each pixel is a painted ping pong ball swinging back and forth.
