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 SEVEN SEGMENT DISPLAY (SSD) INTERFACE

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.
