ATmega32 Controlled “Persistence of Vision” Display
Journal Title: International journal of Emerging Trends in Science and Technology - Year 2014, Vol 1, Issue 7
Abstract
This paper explains the project which includes design and fabrication of a display based on Persistence of vision. The objective of the project is to create virtual display in air. A class of display device described as "POV" is one that composes an image by displaying one spatial portion at a time in rapid succession (for example, one column of pixels every few milliseconds). A two-dimensional POV display is often accomplished by means of rapidly moving a single row of LEDs along a linear or circular path. The effect is that the image is perceived as a whole by the viewer as long as the entire path is completed during the visual persistence time of the human eye. A further effect is often to give the illusion of the image floating in mid-air. For building this project, requirement is just a small 40 pin microcontroller, a position encoder, and SMD LEDs
