    LED Blinking using 8051

    To design LED blinking using 8051, we required Keil5 software and Proteus software. Keil software is used to write a program for 8051 in assembly or Embedded C. Proteus is used to design 8051 LED blinking circuit and test keil program.

    Assembly Program:

    org 00h;
    led equ P2.0; // set LED pin
    up:setb led; // to turn ON LED
    acall delay; // Call delay
    acall delay;
    acall delay;
    clr led; // to turn off LED
    acall delay;
    acall delay;
    acall delay;
    sjmp up
    delay : // Delay Program
    mov r1,#0f0h;
    l1:djnz r1,l1;

    Program in Keil Software

    Circuit Simulation in Proteus software.
