Abstract
In this paper, we present the design & development of a magical fan. The persistence of vision, an optical phenomena that operates in the background to recreate a series of visual pictures in a motion picture, is the basis of how the Propeller LED Message Display operates. The majority of current display grids use many LEDs, which uses a lot of energy. Virtual grids are used in the current work to cut down on the amount of LEDs. By aligning eight LEDs in a row on a propeller, virtual grids can be created. The propeller is rotated quickly to produce virtual grids for showing brief messages that can be utilised as a display gadget in marketing and advertising campaigns. The POV display uses less power than traditional dot-matrix screens. The work presented here is the mini-project work of the 2nd sem students of electronics & communication engineering department of dayananda sagar college of engg., bangalore.
