Description Introduction:
EVM is capable of saving considerable printing stationery and transport of large volumes of electoral material. It is easy to transport, store, and maintain. It completely rules out the chance of invalid votes. Its use results in reduction of polling time, resulting in fewer problems in electoral preparations, law and order, candidates' expenditure, etc. and easy and accurate counting without any mischief at the counting centre. It is also eco friendly.

Our EVM consists mainly of two units - (a) Control Unit (CU) and (b) Ballot Unit (BU) with cable for connecting it with Control unit. Both the units consists of one microcontroller (8052) each. The CU consists of one LCD, one hex keypad and a couple of switches, while BU consists of a candidate panel, a votecast panel and a buzzer, etc.

This project is based on assembly language programming. The software platform used in this project are Keil uVision3 and SPIPGM37.

Important Information:
Please Read this carefully as explained to me by author

author wrote ...
i forgot to mention one thing missing in report n coding as well.
actually, in main function of control unit program as soon as controller
enters in it check the value of variable named "status" that resides in
EEPROM. If status is 1 then voting start else no voting.

if the EEPROM is new or fresh, status will have some garbage value
or 0xFF. which can be a problem on first startup.

So a small program is written to clear that status byte.

After you finish making the hardware. You have to do the following things:

1. Load cufirst.hex file in your controller.
2. Run your circuit.
3. Wait for 2-3 seconds.
4. Load voting.hex which is the real control unit program.
5. Run it.


Please use forum if you have any problem.

if you give me chance
i suggest that we use finger-print sensor so as to ensure that the one votes only for one time .
when he tries to vote for the second time he will be detected by comparing his finger-print that stored at the first time with the second one .
thanks

i'd like to explain a bit abt how dis EVM and other EVM's dat r currently in use, avoid dis thing of "having more than one vote by a single person". when a voter presses d button on ballot
unit, one vote gets counted (dis thing takes some micro/milliseconds), after dis d ballot unit gets disabled (dis is
done thru programming), ie, even if smone presses a button frm ballot unit, no vote wud get counted.( n no human
being can be fast enuf to press a button at a difference of few micro/ millisec) now d ballot unit gets enabled again by
pressing a "ballot button" provided at d control unit panel, n dis button is under direct control of presiding officer, so unless he presses dis button, d ballot unit remains disabled.

so, dont u think dat finger sensor wud lead to unnecessary complexity?? wats ur opinion?

regards,
geetika

hi geetika,
nice of u to contribute ur project.

@ mussab, really nice suggestion given. would have been really useful even for a real voting scenario to pervent bogus voting.

thanq sir.... d reason of contributing dis project is dat i owe dis project to dis very site, d forum n sm ppl like...... i need nt mention d names again,isnt it
n dis ws d only way i kud return a bit of wat i hav recieved

ajay sir,
dont u think dat it wud be better to hav d ckt of controlunit on dis page instead of d pic of microcontroller panel??? wat do u say?
regards,
geetika

i think this circuit diagram should more discriptive...
its a great idea to design such voting machine
but it should problem free...
thanks

hello azam,
can u pls suggest wat other details should be there in this circuit diagram....?? i'll improve it accordingly.

i would also like to tell u dat dis is not simply an idea..... its a fully functional n problem free voting machine
