In this project we are using fingerprint module to check weather a person is authorized or not. If person is authorized then only access is given for voting. We have used four push buttons for four different parties. When any voter presses any one of the four buttons then corresponding voting count value will increment by one each time. The moderator can press result button to see the results. When the “result” button is pressed, arduino processes and calculates the total number of votes of each party and shows it on 16×2 LCD display.
