LED Blinking using 8051

To design LED blinking using 8051, we required Keil 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
