Electronic voting machine has now replaced the traditional mechanism of voting due to several advantages like security, automatic counting etc. Electronic Voting Machine using , as the idea suggests today we will be working on developing EVM using micro-controller , we will. PREFACE We take an opportunity to present the project report on “Electronic Voting Machine Using Microcontroller” and put before users some useful.

The solder wire was of smaller thickness. When the stop button is pressed, the names of the candidates are displayed along with their vote counts. For a website 1. Electronic Voting Machine Project Kit.

Buttons are typically made out of hard material, usually plastic or metal.

The Project Electronic Voting System is an interesting project which uses microcontroller as its brain. Your email address will not be published. Various fault-tolerance and security issues are delegated to the platform itself, therefore relieving the application designer from accommodating these features in the application design itself.

This LCD based electronic voting machine is designed for four candidates.

LCD based voting machine using 8051 microcontroller (AT89C51)

As soon as the user votes for a candidate by pressing one of the switches, the value of the corresponding variable is epectronic by one. Buttons are most often biased switches, though even many un-biased buttons due to their physical nature require a spring to return to their un-pushed state.

A preset is a three legged electronic component which can be made to offer varying resistance in a circuit. Our glimpse into the code of such a system reveals that there is little difference in the way code is developed for voting machines relative to other commercial endeavours. We hope that you have got a better understanding of this concept.


Compilers are programs used to convert a High Level Language to object code. After some delay, the result is displayed which could be either declaration of the winner candidate or the candidates with a clash of their number of votes.

We owe it to ourselves and to our future elecgronic have robust, well- designed election systems to preserve the bedrock of our democracy.

It is applied in an electronic circuit for adjusting circuit resistance to control voltage or current of that circuit or part of that circuit This is micro version of variable resistor. An EVM can record a maximum of votes and can cater to a maximum of 64 candidates.

The on-chip Flash allows the program memory to be reprogrammed in-system or by a conventional non-volatile memory programmer.

Every voter gets support from the voting officer. When a switch is bounced, the system recognizes the bounce by a small beep sound. Electronic Voting Machine Using Microcontroller.

The system is fully controlled by the 8 bit microcontroller 16FA which has a 8Kbytes of ROM for the program memory. It is still important to verify somehow that the binary program images running in the machine correspond to the source code and that the compilers used on the source code are non-malicious.

Anywhere where majority opinion is to be found out. This article discusses complete review about voting devices, Issues and comparison among the voting methods votibg biometric EVM.

LCD based Electronic Voting Machine Project using Microcontroller

We also acknowledge with thanks Prof. In this paper we describe the design, construction and operation of a digital voting machine using a microcontroller profoundly. In this proposed system, one port is devoted to 8-push button switches for 8-contestants, and a master switch for voting officer.


Limited no of candidates. This will enable the voter to cast his vote by pressing the blue button on the balloting unit against the candidate and symbol of his choice. Simulation helps you understand hardware configurations and avoids time wasted on setup problems. We thank our beloved Principal Dr. The BC transistor is a general-purpose transistor in small plastic packages.

First, we discussed the problem of keeping ballot secrecy to a certain extent in the case electtonic a corrupted doting machine or voting authority.

Varsha J Shah, for her continued support and encouragement and motivating us. This situation continued till election scene was completely changed by electronic voting machine.

The password is entered by making use of a keypad. This LCD based electronic voting machine is designed for four candidates. Third, we discussed in detail the possibility of contesting an election based on the evidence provided by the verifiable election scheme.

However, this was only a proof of concept and for a practical application the usability of this approach needs to be further improved. Skip to main content. No more ballot paper, ballot boxes, stamping, etc.

The Init start switch initializes the voting system when pressed, while the Stop switch ends the voting and displays the poll results on LCD screen.

It helps in keeping the secrecy of voting data. As soon as the user votes for a candidate by pressing one of the switches, the value of the corresponding variable is increased by one.
