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.

Proteus VSM comes with extensive debugging features, including breakpoints, single stepping and variable display for a neat design prior to hardware prototyping.

It reads program written in ROM memory and executes them and do the expected task. For an authored book 1. This project is designed for 8-contestants. We record our thanks to our madhine in our class for interaction usig help during the course of the Mini Project. 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 as maintaining the Linux operating System.

Electronic Voting Machine Using Microcontroller (AT89C51)

The surface is usually flat or shaped to accommodate the human finger or hand, so as to be easily depressed or pushed. Furthermore, any doubts regarding this concept or to implement electrical projectsplease give your feedback by commenting in the comment section below. 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.

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. A Polling-officer switch is provided to avoid numerous polling by only voter.


Both the computer and the device agreed on a speed of information – ‘bits per second’. What is Web Browser.

LCD based voting machine using 8051 microcontroller (AT89C51)

The EVMs are devised and designed by Election Commission of India in collaboration with two public sector undertakings EVMs usig first used in in the by election to Parur assembly constituency of Kerala for 50 polling stations.

It is used to carry data. Preset resistors are directly mounted on circuit board and adjusted only when the circuit is built. This switch is provided for enabling the keypad in voting mode.

More than two billion crystals are manufactured annually. Conductors on different layers multi layers are connected with plated-through holes called via A via is an electrical connection between layers in a physical electronic circuit that goes through the plane of one or more adjacent layers.

When subroutine is completed then the execution of main program starts as usual. For this purpose, Microcontroller has an on-chip oscillator which works as a clock source for Central Processing Unit. The advantage of this memory is that it stores data in memory even after power is turned off.

Convenient on the part of voter.

It can be used to find the general opinion of people on various issues. This is then converted to microcintroller DC using a bridge rectifier.

Normal light bulbs produce light by heating a metal filament until its white hot. 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. The leads of the components were kept clean before soldering, with the use of sand paper. Anywhere where majority opinion is to be found out. It used to address memory locations.


Even more important is the timely announcement of results. The microcontroller based digital votong for Doors is an access control system that allows only authorized persons to access a restricted area. It is applied in an electronic circuit for adjusting circuit imcrocontroller to control voltage or current of that circuit or part of that circuit This is micro version of variable resistor. Skip to main content. The input part consists of a set of six tactile switches.

Microcontroller Based EVM-Electronic Voting Machine

Quartz crystals are manufactured for frequencies from a few tens of kilohertz to hundreds of megahertz. Ever since its first releases, all software source code firmware, PC application and hardware schematics are open to the public. These resistors are quite cheaper than standard variable resistor available in the market. Active involvement of the public in machins formation of the government is an essential aspect of a democratic government. Votin provision of casting votes for the candidates has been provided through four of these switches.

Microcontroller has 8 bits data bus.

After every cast of vote, the subsequent count can be seen on LCD. The system is fully controlled by the 8 bit microcontroller 16FA which has a 8Kbytes of ROM for the program memory.

Log In Sign Up. C pin no 1 should be made sure at right hole.
