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.

India is the largest democratic country in the world. Active involvement of the public in the formation of the government is an essential aspect of a democratic government. This is confirmed by an microocntroller. Conducting elections in a populated country like India is a difficult task. Even more important is the timely announcement of results.

This is required maxhine bring steadiness in the governance and stable financial growth of the nation. To overcome this problem, An EVM electronic voting machine is an answer to all these complications.

In the worldwide, several countries have shown their interest in learning the mechanism behind this powerful machine.

In the year these devices were first used in the by-election to the Assembly Constituency of Prarur, Kerala for fifty polling stations. The electronic voting machine saves time, money and manpower. It helps in keeping the secrecy of voting data.

At the end of the elections, you can check the result by pressing a button. The Project Electronic Voting System is an interesting project which uses microcontroller as its brain.

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 push button switches for eight contestants, master switch for polling officer. This is then converted to the DC using a bridge rectifier. The AC ripples are filtered out by using a capacitor and given to the input pin of the voltage regulator LEDs are semiconductor devices are made out of silicon,When current passes through the LED, it emits photons as a byproduct.


Normal light bulbs produce light by heating a metal filament until its white hot. LEDs present many advantages over traditional light sources, including lower energy consumption, longer lifetime, improved robustness, smaller size and faster switching. This buzzer is a piece type audio signaling device, which has a piece element and a oscillating circuit inside which oscillates the piezo brass base plate, which when given voltage difference produces the sound of a predefined frequency.

The BC transistor is a general-purpose transistor in small plastic packages. Whenever base is high, then current starts flowing through the base and emitter and after that only current will pass from collector to emitter. Compilers are programs used to convert a High Level Language to object code.

Desktop compilers produce an output object code for the underlying microprocessor, but not for other microprocessors. For example, compilers for DOS platform is different from the Compilers for Unix platform So if one wants to define a compiler then compiler is a program that translates source code into object code. The advantage of this memory is that it stores data in memory even after power is turned off.

This is an interesting project designed with a microcontroller which works as a brain.

This project is designed for 8-contestants. Electorates can poll their vote to electronlc one of the competitors. In this proposed system, one port is devoted to 8-push button switches for 8-contestants, and a votiny switch for voting officer. The simple programming of this project can be written in assembly language, and it is dumped into the microcontroller to accept votes and, to keep calculating the total votes polled.


A Polling-officer switch is provided to avoid numerous polling by only voter. Every voter gets support from the voting officer. If the officer issues sanction with microcontrolper control switch, then only the elector can poll his vote. This polling of approval is specified by a long buzzing sound. An LCD display is offered to display the total votes count polled, and separate contestant -vise votes polled.

A beeper is offered for audio effect of the switch bounce.

When a switch is bounced, the system recognizes the bounce by a small beep sound. If electronid elector tries to vote several times a lengthy beep sound is produced. The advantages and application of electronic voting machine include the following.

Thus, this is all about EVM-electronic voting machine and its applications. We hope that you have got a better understanding of this concept.

Furthermore, any doubts regarding this concept or to implement electrical projectsplease give your feedback by commenting in the comment section below. Here is a question for you, What are the advantages of EVM?
