Hard Drive Persistence of Vision (HDPOV) using arduino

The platter of a hard drive spins well over sixty times a second. If a narrow slot was cut into the platter to allow LEDs to shine through, we can achieve flicker fusion and trick the eye into seeing a stable image. This phenomenon is known as persistence of vision (POV). There are many examples of LEDs being used for POV, building an image by moving the LEDs or having the observer move relative to them. Th ...
