POV or persistence of vision is a theory where an afterimage is thought to persist for approximately one sixteenth of a second on the retina, and believed to be the explanation for motion perception. This technique is commonly employed in projectors where the frames are cycled so fast that it seems continuous to the eye. In this project you could remotely control a POV display which has the ability to display a heart image, an analog clock and a predefined word.
Another great thing about the project is that a sort of wireless power has been implemented in the device using simple transformer with a LC resonant circuit. The mathematics involved in the project is a little complicated but completely void of tough equations. Once understood it can be easily implemented with the help of additional libraries. The principal component used in our project is the Atmel ATmega1284P microcontroller which connects the IR transmitter, receiver along with LED’s and motor control for POV. A really beautiful project but you might have to make changes to it to suit your needs and to alter the display text. This should not me much of an issue as the concepts involved in the present design are explained in detail on project website.
