Persistence of Vision (POV) is an optical phenomenon where an image remains on the retina for a short time even after the object is no longer visible. This project implements a POV Display using an Arduino Nano and a rotating set of LEDs. By leveraging the phenomenon where an image remains on the retina for ~1/16th of a second, it creates the illusion of characters or symbols floating in the air.

1.Arduino IDE to run Code.ino file
2.Serial Bluetooth Terminal app for Bluetooth module
1.Follow the circuit diagram and make the proper connections of all the components.
2.Load the Code.ino file to the Nano.
3.Connect the Bluetooth module to the app. It will appear as HC-05 and the password will either be 1234 or 0000.
