The microcontroller based voting machines made the process of voting and counting the voted lot easier than before. Previously the votes were marked in paper which are then stored safely in a box and inside a well secure room for days. The process of separating the votes and counting them manually may take a lot of days. But after finding the electronic voting machine the votes can be marked without using papers, which makes the voting process eco-friendly. Moreover it makes the counting process faster and the results can be announced in a comparatively shorter period of time.
This project is all about how we can make use of internal EEPROM of the AVR for storing data for future purpose. In this project we are making an Electronic Voting Machine (EVM) using the EEPROM of the AVR. As in the case of normal EVM, there is a control unit and a ballet unit. The ballet unit can be used to cast the vote only after it is enabled by pressing a key in the control unit. After casting a single vote the ballet unit will get disabled again. Each and every time a user press a key the LCD displays which candidate he voted for.
