Patterns Display using POV (Persistence of Vision)
Author:- M.Sundeep Goud( sundeep.2488@gmail.com )
The project mainly works with the principal of POV(persistence of vision). Persistence of vision is the phenomenon of the eye by which an afterimage is thought to persist for approximately one twenty-fifth of a second on the retina.[citation needed]The myth of persistence of vision is the belief that human perception of motion (brain centered) is the result of persistence of vision (eye centered). The myth was debunked in 1912 by Wertheimer[1] but persists in many citations in many classic and modern film-theory texts.A more plausible theory to explain motion perception (at least on a descriptive level) are two distinct perceptual illusions: phi phenomenon and beta movement.
In this project i am going to control 24 LED's with the help of ATMEG16A Microcontroller. The LED's are arranged in a single Row on a rectangular PCB. this LED's +ve terminals are directly connected to I/O ports of ATMEGA16A and -ve ends are connected to 220 ohms resister then it is grounded. Resisters are used to control the flow of current in LED's.
The whole setup was connected on a 1000 RPM DC motor so that the LED's start rotating and forms Patterns as we can see in the above viedo
