In this project I want to show you the Persistence Of Vision (POV) to generating a rotating message in the air using only 10 LEDs. It is also called “POV stick”. The apparatus consists of flashing and rotating 8 LEDs at a frequency such that the human eye does not notice a discontinuity in the formation of the message. All characters that forms the message will be swept (column by column) and the angular rotation speed of the device, combined with the flashing speed of the LEDs will generate the image in the air as if it were for and complete message.”
