ABSTRACT
EVM has made the voting procedure simpler. It is a revolutionary method preferred to traditional voting, as it is risk defective. It is advantageous because it includes features such as avoidance of invalid votes (booth capturing), reduction of counting time and the expenditure incurred on manpower deployment.
In our project we are using 8051 microcontroller to build an EVM easily and simple to operate. A polling officer controls the voting process. He/She grants permission to the voters to vote their selected candidate .Each person can vote for one candidate only. In our project we have allotted 9 keys for 9 candidates each .A candidate can be voted for a maximum of 10000 votes. Any voter is allowed to vote between 7am-5pm only. When a vote is voted a beep sound is indicated by a buzzer. Finally results are being displayed on the LCD, when polling officer enters the password.
The AT89C52 is an 8-bit microcontroller with 8k bytes of flash ROM, 256 bytes of RAM and is preferred in using this micro due to its quick programming and ease of use.
The time in accordance to a particular application ahead is set by the user through a keypad. In this we use an open push button switch to set the time/date. When the button is pushed, we need to opt one of the applications among the three. When the user selects a particular application through keypad, the Buzzer blows up indicating a beep sound, at the instant where the time matches with a specific application’s time.
