EVM-Electronic Voting Machine Introduction • The project is designed for eight contestants. Voters can poll their vote to any one of the contestant. In this project, one port is dedicated for 8 push-button switches for eight contestants, and a master switch for polling officer. A simple yet powerful program is written in assembly language and is burnt onto the microcontroller to accept votes and to keep counting the total votes polled. A Polling-officer switch (master) is provided to avoid multiple polling by a single voter. Every voter gets approval from the polling officer. If the polling officer issues approval with his control switch, then only the voter can poll his vote. http://www.edgefxkits.com/
