EVM-Voting-System-By-Hrishi

A GUI-based Electronic Voting Machine (EVM) application built using Python and Tkinter. This project demonstrates a simple yet effective implementation of an electronic voting system that includes voter authentication, live result visualization, theme toggling, and data export capabilities.

Features

1. Admin Panel

• Add candidate names for the voting process.
• Reset the entire voting system to start fresh.
• Password-protected access to voting results.

2. Voter Panel

• Voter authentication using phone numbers (each phone number can vote only once).
• Cast votes by selecting from a list of candidates.

3. Results Panel

• Admin-only access to live voting results.
• Graphical visualization of voting results using pie charts.
• Export results to CSV and JSON formats.

4. Theme Toggle

• Switch between light mode and dark mode for better visibility.

5. Data Management

• Automatically prevents double voting by maintaining a record of phone numbers that have already voted.

     • Voter authentication (add_voter).
     • Casting votes (cast_vote).
     • Displaying and exporting results.

2. EVMApp Class

   • Handles the GUI of the application using Tkinter.
   • Manages interactions between the user and the EVM class:
     • Admin panel for adding candidates and viewing results.
     • Voter panel for casting votes.
     • Results panel for viewing and exporting data.
   • Implements the theme toggling feature.
