Make a POV clock
In this project we will explain how to make a POV clock in an easy way. POV stands for persistence of vision. It is a kind of optical illusion in which a visual image seems to persist even when the rays of light cease to enter our eyes because they are interrupted for very short instances. You can display any text or image you want with it.
We use a series of LEDs, Arduino Nano, a voltage regulator (7805) that allows you to lower the power supply voltage from 9v to 5v and a generic DC motor.
