Abstract: This paper describes the 8051 microcontroller interrupts concepts, programming and applications. The applications include an interfacing of LEDs, Stepper Motor, DC Motor and Serial Port with micro controller and these are controlled by external interrupts (INT0, INT1) signals through switches. In this experiment P89V51RD2 8-bit microcontroller is used to program the interrupts to flash LED’s, rotate the stepper motor and DC motor through clockwise and anti-clock wise directions. The Hardware description and software developments are presented in this paper.
