Description

Electronic Voting Machine with Managed Control Unit


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

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.

What's New?
1. Schematic updated
2. Added proteus simulation if you want to try it before building it
