1.ABSTRACT:
Electronic voting (also known as e-voting) is voting using electronic
systems to aid casting and counting votes. Electronic voting technology can
include punched cards, optical scan voting systems and specialized voting kiosks
(including self-contained direct-recording electronic voting systems, or DRE). It
can also involve transmission of ballots and votes via telephones, private computer
networks, or the Internet.
2.OBJECTIVE:
The main goal of this project is developed to improvise present voting
technique by electronics with password protection.

HARDWARE REQUIREMENTS:

Button.
SOFTWARE REQUIREMENTS:
Keil compiler uVision 4, Language: Embedded C or Assembly, WLPRO Programmer
4.METHODOLOGY:
This project is developed to improvise present voting technique by
electronics. The main modules in this project are 4X4 Keypad, Switches,
MSP430 controller unit with LCD display and output.
The transmitter will be there in Election Voting Center.. The transmitter
module has 4X4 Keypad for password entry because each person should have
unique password for voting.
After entering the password, if the password is correct then he can vote
for his favorite party by switching the appropriate switch, at this level voting of
that particular person has finished. After pressing the switch that information
will send to MSP430 then the MSP430 controller analyses the signal and then it
provides one voice announcement like Thank You for Voting. After receiving
the signal the from the switch the MSP430 controller will activate the Buzzer or
DC Motor or Visual Indication based on the application.
5.ADVANTAGES AND DISADVANTAGES:
ADVANTAGES:
Electronic voting machines can be made fully accessible for persons with
disabilities.
Electronic voting machines are able to provide immediate feedback to the voter
detecting such possible problems as under voting and over voting which may
result in a spoiled ballot. This immediate feedback can be helpful in successfully
determining voter intent.
Environmental effects of EVMs: For each national election alone it is estimated
that about 10,000 tons of ballot paper (roughly 200,000 trees) would be saved.
Invalid votes can be reduced by use of EVMs. Bogus voting can be greatly
reduced by the use of EVMs.
It will be easier to transport the EVMs compared to ballot boxes as EVMs are
lighter, portable and come with polypropylene carrying cases.
The vote-counting is very fast and the result can be declared within 2 to 3 hours
as compared to 30–40 hours, on an average, under the ballot-paper system.
The EVMs reduce the time in both casting a vote and declaring the results
compared to the old paper ballot system.
DISADVANTAGES:
Cost effective.
Not useful unless all countries adopt it.
6.APPLICATIONS:
This project can be implemented in Schools, Colleges and Companies for any
stream.
Restricted places for election voting.
Wherever secrecy is important there we can use it.
7.CONCLUSION:
The proposed Electronic Voting Machine Using MSP430 With Voice
Feedback System has been implemented successfully and is tested on hardware.
Experimental results verify the effective developed operation. This technology
can give a better security for voting system in Elections.
