Abstract

This project presents yet another type of display, which uses the phenomena of persistence of vision to its advantage. Human eye can sense difference between two sets of images only if they change at a rate slower than 24 Hz. If the rate is higher, it is perceived as continuous motion by the human brain. Thus a single array (column) of LEDs is programmed to glow in a sequence such that when that array is rotated, it displays a certain message. This message is clearly seen only if the array is rotated at a certain speed. This display uses 20 LEDs arranged in a single array (column), soldered upon a rod that is rotated by a motor. This entire project is run by the Arduino uno microcontroller board. This display has certain advantages over its competitors, mainly lesser power consumption, less complexity and better aesthetic value, making it an apt device to display short messages.
