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.

It helps in keeping the secrecy of voting data. After some delay, the result is displayed which could be either declaration of the winner candidate or the candidates with a clash microconhroller their number eletcronic votes.

Governments around the world are increasingly considering the replacement of traditional paper-based voting schemes with electronic voting systems. It is used in general elections for choosing candidates to represent people at various stages.

Whenever base is high, then current starts flowing through the base and emitter and after that only current will pass from collector to emitter.

Microcontroller is used in embedded systems to control the operation of machines. Here we have used 16 x 2 Alphanumeric Display which means it can display two lines with maximum of 16 characters in one line. The task of completing the project though being difficult but was made quite simple ,interesting and successful due to deep involvement and complete dedication of our group members. Buttons are typically made out of hard material, usually plastic or metal.


The input part consists of a set of six tactile switches. Advantages is 1 real time simulation.

The voting is started by pressing the Init switch after which the user is prompted to vote. This makes polling much fast and is more reliable then ballot papers, by preventing bogus voting to a great extent. Electronic Voting Machine Using Microcontroller. This project is designed for 8-contestants.

LCD based Electronic Voting Machine Project using Microcontroller

It can be used to find the general opinion of people on various issues. This could be used micgocontroller voting purpose at any required place.

Additionally, with simulation, you can write and test applications before target hardware is available. The simplest way to do this was to pass a series of 1s and 0s to the computer.

Microcontroller Based EVM-Electronic Voting Machine

Microcontroller has 8 bits data bus. This is then converted to the DC using a voying rectifier. C socket is suggested. Mchine just a name for a standard that has propagated from generation to generation of computers. This article discusses complete review about voting devices, Issues and comparison among the voting methods and biometric EVM. This switch is under the control of voting authority.

Skip to main content. Advanced PCBs may contain components – capacitors, resistors or active devices – embedded in the substrate.

Here is a question for you, What are the advantages of EVM? Each component should be done neatly.


After every cast of vote, the subsequent count can be seen on LCD. Even if one presses that button further or any other button, no further vote will be recorded. No one votinv the manufacturer can change the program once the controller is manufactured.

The microcontroller based digital lock for Doors is an access control system that allows only authorized persons to access a restricted area. Thus, this is all about EVM-electronic voting machine and its applications.

The count of votes is electrnic in four different variables.

Electronics have changed a bit. The EVM project an ambitious attempt to create an open-source voting system with a voter-verifiable audit trail a laudable goal The model where individual vendors write proprietary code to run our elections appears to be unreliable, and if we do not change the process of designing our voting systems, we will have no confidence that our election results will reflect the will of the electorate.

LEDs present many advantages over traditional light sources, including lower energy consumption, longer lifetime, improved robustness, smaller size and faster switching.
