In this section i will tell you about the POV coding using PIC16F877A in C language. Persistence of vision is the phenomenon of the eye by which an afterimage is thought to persist for approximately one twenty-fifth of a second on the retina.
My plan is to use the fan from PC power supply; for rotating purpose. Now first of all i want to tell the two things. 1st i don't have smaller MCU that is why me using 40 pin, you can also use 28 pin if you have any. 2nd due to my hardware design fault, actually soldering fault, i missed the RB0 pin; so to compensate it i used RD0. You can change the coding if you want for your ease.
