Objective

The few technical disadvantages are given as:

Microprocessor based design, which requiresa no. of supporting components like memory,

peripheral interface, etc.No security against illegal viewing of results,

as presiding officer can view the results

without any difficulty.Less user friendly due to two seven segment

displays

Introduction

All these faults motivated us to make this newenhanced EVM. The faults which are eliminatedare summarized as follows:

Microcontroller replaced microprocessor, which

made the EVM closer to real time operationmaking it faster, more reliable and unique. Password protection is provided to save data

from being accessed by unauthorized personnel.Presiding officer can only conduct voting process,

doesnt have any access over results. More user friendly and interactive 128 pixel LCD

display and user friendly touch screen interface.

Description

The EVM consists of control unit (CU) andTouch Screen Interface.

Both units work independently and in

collaboration with each other. In Voting mode:

User is directed to select desired candidate.

After candidate selection, user is asked forconformation of his/her vote.

Individual votes are stored in EEPROMmemory.

Description

For security of data master mode is password

protected

In Master mode:

User can access data.

Transfer data to PC via RS232 interface.

Individual votes can be displayed on PC.

Salient Features

Fully micro controller based interface

On board serial EEPROM for data retention andsecurity. (No require battery back up)

128 pixel touch screen 128 pixel LCD Display to display the Information

3 x 4 Keypad for Password entry

Four digit password protection for security and

data backup Low power consumption

Powered by 12V DC power supply OR batteries

Conclusion

In total, the complete system (including all the hardware

components and software routines) is working as per the

initial specifications and requirements of our project.

Because of the creative nature of the design, and due tolack of time, some features could not be fine-tuned and

are not working properly. So certain aspects of the

system can be modified as operational experience is

gained with it. As the users work with the system, they develop various

new ideas for the development and enhancement of the

project.

Application and Future Scope

Fast track voting that can be used in smallscale elections

To conduct opinion polls during annual shareholders meeting

To conduct general assembly elections No. of candidates can be increased Could be interfaced with a printer

Could be interfaced with a PC and result canbe stored in the central server This result can then could be relayed on the

network to other election offices
