Generally Digital Voting Machine is one kind of microcontroller based
machine which can be performed in election . Once i had made Digital
Voting Machine and i was in 5th semester . Today I am going to share an
upgrade version of it . Here in this, i used EEPROM of PIC 18f2550
so that data can be saved from electricity failure .
***Controling Button :
This is the main head of all other buttons . Without having permission
of this button ,any button can't perform . Without permission it's
instructions will not be taken . This will be in the presiding officer's
room .Once he will press the button and all other buttons will be
permitted to perform for one time . If any key or button will be pressed
, it will perform for one time and it will disable the system to take
vote . So , one person will be able to vote for one time & voter
will not be able to do that without permission of PO . The video will
make clear about this .
***Status View Button :
For security we are hiding the voting status from voter and Only PO can
view this . At first PO have to press "Control Button " and LED 1 turns
on . Then will have to press "View Status" button and current status
will be shown only for a little time before getting back to the previous
stage with turning on LED2.
