Voting machine Prototype

Description:

This project is design for the student to make them understand

the technology used in a now a day’s voting machine system, which is used in

whole world. These voting machines are equipped with the CPU, which control

the voting machine. The voting machine is programmed for the specific

operation. Every operation on the voting machine is defined is display on the

Computer Monitor.

Projects summary:

  In this project we try to give the Idea of prototype voting

machines. We are using micro controller AT89C51 for controlling the voting

operation. The voting machine is designed for three Political parties. There is a

Monitor display for showing the status of voting by interfacing the voting machine

with the PC. For connecting the voting machine with PC we use the Hyper Terminalcommunication system, which are already come with the Window2000\XP operating

system.
