The goal was to design a home made LED Display that can be expanded to bigger sizes with minimal costs. Unlike other systems, on this one the image gets scanned mechanically and the image is created by using the POV effect (persistence of vision). There are 32 RGB LED used in the project but you can easily increase the number of LED’s. The author attached the system to a spinning fan, and the images started to appear.
