Seven Segment Display which is most commonly known as SSD is an output device which can be used to display information. As discussed in my previous post, it is necessary for a system to have proper input/output devices for assisting the user and SSD serves the very same purpose by displaying some useful information to the user. You can easily connect/interface it with 8051 MCU for output once you understand it properly. After reading this article, you will get to know everything about it.
A beginner's guide to 8051 microcontroller with special emphasis on programming and hardware implementation.

8051 SWITCH INTERFACE
It is necessary for every system to have proper user interface - which makes it user friendly and easy to operate. For instance, imagine using your computer without the monitor (display), keyboard or mouse? It's not even possible to operate it without these essential components as they help you either in entering data (input) to the PC or seeing the results on screen (output). Similarly, an embedded system (the one involving microcontrollers such as 8051 in our case) also require input/ouput devices to be user friendly. A switch can act as an input device to the microcontroller unit (MCU) and this post is all about interfacing/connecting it to the 8051 MCU.

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.
