Keypad LCD Display Project shows you how to interface 4×4 keypad and 16×2 LCD Display at same time with 8051 architectures micro-controller.
Schematic For LCD keypad Display
Moving Text LCD Display Project is helpful for making moving text display.
In this projects the circuit is included for interfacing of the 16×2 alphanumeric LCD with 8051 microcontroller. In this project the LCD Displays is connected to the 8051 microcontroller in 4 bit mode to simplifying the complexity of the circuit.

Keypad Matrix Scanning technique is most commonly used technique for taking input in the microcontroller.
This is a project in which we used to take input from Keypad Matrix and provide output according to the input provided.
The Input is provided by the keypad matrix, and output is displayed on the 7 segment.
For this first of all we need to scan the input keypad matrix, after scanning we put the corresponding number on the 7-segment dispay.
