Persistence of vision refers to the optical illusion that occurs when visual perception of an object does not cease for some time after the rays of light proceeding from it have ceased to enter the eye (more about persistence of vision here).
One of the cool kits made by Adafruit is the MiniPOV 4, a DIY Full-Color POV Display. The MiniPOV creates this illusion and allows you to paint with light in mid-air. In this quest, you are going to create the MetroPOV, a circuit that uses Persistence of Vision and the Adafruit Metro. You'll learn about persistence-of-vision, optical illusions, and create your own drawings.
Let's paint the sky with the Metro!
