8051 INTERFACING WITH LED, SWITCH, SSD AND KEYPAD

This is a wrap-up article for interfacing hardware with 8051 microcontroller. It's a combo deal for starters because this time, I have interfaced switches, LEDs, seven-segment-display and keypad all at the same time. I have already talked about them, individually, in my previous articles but for better understanding I think it's important to know how they work together. It will also give you some idea about dividing your code into segments and pieces which ultimately polishes your code writing skills.

8051 LED TOGGLE PROGRAM CODE

You might have seen a "Hello World!" program code example while learning some programming language. While it is useful for getting familiar with the basics of that language, it also gives you a head start in that environment. If you ever want to learn some new programming language, you might want to Google out a "Hello world!' program code to get started. The code I am about to discuss serves the same purpose for the 8051 microcontroller because it is the most simplest task to perform. Play close attention if you want everything to work properly.
