INTRODUCTIONINTRODUCTION It is a project based on the theme to It is a project based on the theme to

work efficiently in Voting. work efficiently in Voting.

By this project we can terminate the By this project we can terminate the unnecessary booth capturing & unnecessary booth capturing & unwanted voting for the voter and unwanted voting for the voter and they get services in more they get services in more comfortable way.comfortable way.

TECHNICAL REVIEWTECHNICAL REVIEW The project employs the use of ATMEL The project employs the use of ATMEL

series microcontroller AT89C51.series microcontroller AT89C51. It has some special features –It has some special features –

1. 4K Bytes of In-System Reprogrammable Downloadable Flash Memory and 0-24 MHz operation.

2. 2K Bytes EEPROM.3. 32 Programmable I/O Lines.4. Two 16-bit Timer/Counters. 5. 256 x 8 BIT internal RAM.6. It has 4 I/O ports.

ADVANTAGESADVANTAGES The EVM is compact. Further, the EVM operates on a The EVM is compact. Further, the EVM operates on a

battery power source; making it independent and totally battery power source; making it independent and totally reliable.reliable.

Once polling is completed, the Once polling is completed, the election results can be can be known instantly at the counting station. This switch is known instantly at the counting station. This switch is located in a sealed compartment of the control unit. located in a sealed compartment of the control unit.

EVM saves considerable time, money and manpower.EVM saves considerable time, money and manpower.

Another advantage is that if several wireless Another advantage is that if several wireless EVMs are networked then this may form a better EVMs are networked then this may form a better solution to booth capturing and vote counting.solution to booth capturing and vote counting.

The networking of wireless EVMs may also The networking of wireless EVMs may also increase the voting percentage as more EVMs increase the voting percentage as more EVMs may be installed and if a citizen supposedly may be installed and if a citizen supposedly lives in Maharashtra and is a resident of U.P lives in Maharashtra and is a resident of U.P then he may cast his vote in his city of living then he may cast his vote in his city of living instead of going back to his native state.instead of going back to his native state.

Voters will be provided with more flexibility.Voters will be provided with more flexibility.

LIMITATIONSLIMITATIONS Electronic voting systems limitation could be the overall Electronic voting systems limitation could be the overall

costs. Software, machines, installations, proper software costs. Software, machines, installations, proper software protection, and validation of results could be expensive; protection, and validation of results could be expensive; even more expensive than paper-based machines. even more expensive than paper-based machines.
