This project demonstrates how to interface a 4x4 keypad with a PIC microcontroller and display the pressed numbers on an LCD. The code is written in Embedded C using MPLAB IDE, and the simulation is done in Proteus. It helps in understanding keypad scanning and LCD interfacing with PIC microcontrollers.
Detects key presses from a 4x4 matrix keypad. Displays the pressed numbers on a 16x2 LCD. Efficient keypad scanning and real-time LCD updates.
Microcontroller: PIC, Programming Language: Embedded C, IDE: MPLAB IDE, Simulation Software: Proteus
The keypad is connected to the microcontroller using GPIO pins. When a key is pressed, the microcontroller scans and identifies the key. The corresponding number is displayed on the LCD in real time.
