Project Title: Electronic Voting Machine

Problem Statement:

This project aims to design and implement a simulated electronic voting machine that allows users to cast votes for candidates using a keypad, with a PIC microcontroller managing the vote tally and an LCD displaying real$-$time vote counts.

Objective:

Develop a simulated electronic voting system where users can cast votes via a keypad, and the system displays vote counts on an LCD.

Components:

$-$ Input Device: Keypad for users to select and cast their vote for different candidates.

$-$ Microcontroller: PIC microcontroller to process the votes and keep track of each candidate's vote count.

$-$ Display Device: LCD to display the current vote counts for each candidate.

Functionality:

$-$ The system will prompt users to vote by selecting a candidate number on the keypad.

$-$ Once a vote is cast:

o The microcontroller will increment the vote count for the selected candidate.

o The LCD will display the updated vote count for each candidate in real time.

$-$ The system should use interrupts to handle keypad input efficiently and timers to refresh the display at set intervals.
