Pov display using ardiuno.
Make a simple persistence-of-vision (POV) display with an Arduino. How Does the POV Display Work? What is POV(Persistence of Vision)? It can be defined in simple words. When a person sees an object, its image remains in the retina of the eye for a time interval of 1/16th of a second. This phenomenon is known as persistence of vision. This phenomenon is used in the POV Display to form images. We turn the LEDs on and off in such a way that the different images overlap each other forming letters. For example: Formation of letter "E" with 5 LEDs 1 2 3 <-- Time 1 1 1 <-- Bulb 1 the 1 0 0 <-- Bulb 2 1 1 1 <-- Bulb 3 1 0 0 <-- Bulb 4 1 1 1 <-- Bulb 5 Each row represents the 5 LEDs we use to make the Arduino POV display and each column is a time interval. Each element in the row represents the state of the LED at that given time. At t = 1 Bulbs 1,2,3,4,5 are ON At t = 2 Bulbs 1,3,5 are ON This way we can visually see the letter E formed by the LEDs but the time inte
