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 EVMs are devised and designed by Election Commission of India in collaboration with two public sector undertakings EVMs were first used in in the by election to Parur assembly constituency of Kerala for 50 polling stations. As soon as a particular button on the balloting unit is pressed, the vote is recorded for that particular candidate and the machine gets locked. It can be used to find the general opinion of people on various issues. For this purpose, Microcontroller has an on-chip oscillator which works as a clock source for Central Processing Unit.

An EVM can record a maximum of votes and can cater to a maximum of 64 candidates. The AC ripples are filtered out by using a capacitor and given to the input pin of the voltage regulator In addition, the AT89S52 is designed with static logic for operation down to zero frequency and supports two software selectable power saving modes.

When the stop button is votinng, the names of the candidates are displayed along with their vote counts. Our contribution to this is an approach where all secret information is encapsulated in the voting machine.

Again we also portray counting system of votes, market survey and macyine analysis. In this project one port is dedicated for push button switches for eight contestants, master nachine for polling officer.

The voting is started by pressing the Init switch after which the user is prompted to vote. LEDs present many advantages over traditional light sources, including lower energy consumption, longer lifetime, improved robustness, smaller size and faster switching. This system allows the user to unlock the device with a password. Skip to main content. Leave a Reply Cancel reply Your email address will not be published.


The two units are joined by a five- meter cable. The advantage of this memory is that it stores data in memory even after power is turned off. Microcontroller has a 16 bit address bus.

It is used to carry data. An LCD display is offered to display the total votes count polled, and separate contestant -vise votes polled. Elections of Bangladesh are conducted most exclusively using electronic voting machines developed over the past three years. Together with a display in the polling place this approach shortens the time window in which an adversary can perform the ballot stealing attack without almost zero risk.

Here we have used 16 x 2 Alphanumeric Display which means it can display two lines with maximum of 16 characters in one line. No one including the manufacturer can ellectronic the program once the controller is manufactured.

LCD based Electronic Voting Machine Project using Microcontroller

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. Preset resistors are directly mounted on circuit board and adjusted only when the circuit is built.

His original design using Integrated Circuits was exhibited to the public in Government Exhibitions held in six cities across Tamil Nadu. A preset is a three legged electronic component which can be made to offer varying resistance in a circuit.

The simple programming microcontorller 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. More candidates mean implies complicated circuits. Varsha J Shah, for her continued support and encouragement and motivating us.

They are provided with an access control system. Help Center Find new research papers in: We hope that you have got a better understanding of this concept. However, open source is a good start. Such open design processes have proven successful in projects ranging from very focused efforts, such as specifying the Advanced Encryption Standard AES [23], through very large and complex systems such machune maintaining the Linux operating System.


In mkcrocontroller proposed system, one port is micrcoontroller to 8-push button switches for 8-contestants, and a master switch for voting officer.

Voters can poll their vote to any one of the contestant. After every cast of vote, the subsequent count can be seen on LCD. Electronic Voting Machine Project Kit.

When the stop button is pressed, the names of the candidates are displayed along with their vote counts. Furthermore, any doubts regarding this concept or to implement electrical projectsplease give your feedback by commenting in the comment section below.

Limited no of candidates. Uding are of two types: Arduino based GPS receiver.

Microcontroller Based EVM-Electronic Voting Machine

Of course, open source would not solve all of the problems with electronic elections. Quartz crystals are manufactured for frequencies from a few tens of kilohertz to microcotroller of megahertz. The on-chip Flash allows the program memory to be reprogrammed in-system or by a ordinary nonvolatile memory programmer.

So the Electronic voting system has to be improved based on the current technologies viz. In fact, we believe that an open process would result in more careful development, as more scientists, software engineers, political activists, and others who value their democracy would elecrronic paying attention to the quality of the software that is used for their elections.

Extra solder was not used in order to avoid a cause of short circuit in the conductive path. Zoom forward to today. The surface is usually flat or shaped to accommodate the human finger or hand, so as to be easily depressed or pushed. 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.
