LED propeller display with android application

This paper mainly emphasizes on the POV (Persistence of Vision) technology with the help some mechanical arrangement, LED, equipment required, and consequently general cost is sliced to extremely moderate cost. Additionally, support and repairing of the display is easy to the point for anybody having a little electronics education can deal with this. All the synchronizing can be executed through programming. It is made utilizing ATmega328 microcontroller, this project utilize the rule of Space Multiplexing and persistence of vision. This propeller display will be mechanically examined and shows the characters in advanced arrangement and data to be shown can be either fed by assembly level program or by an android application using Bluetooth. Produced using scrap it can be utilized anyplace and all over and the most astounding certainty about this propeller display is its perfectly clear. This propeller comprises of only 8 RGB LEDs which are arranged on to demonstrate the display. For building this project, necessity is only an Arduino board, a position encoder, and LEDs. This display can demonstrate the messages, which will require 665 LEDs. So equipment and cost minimization is accomplished.
