DESCRIPTION
This LCD based electronic voting machine is designed for four candidates. The input part consists of
a set of six tactile switches. The switches and 16x2 LCD are interfaced to
microcontroller AT89C51 for various operations and displays.
The provision of casting votes for the candidates has been provided through four of these switches.
These switches are made active high and connected to pins 2-5 (P1^1 – P1^4) of the controller. The
remaining two switches (both active low) are to start and stop the voting procedure. They are
connected to pins 1 and 6 (P1^0 and P1^5) respectively. The Init (start) switch initializes the voting
system when pressed, while the Stop switch ends the voting and displays the poll results on LCD
screen.
