Design and Construction of a Simple Microcontroller Based Conference Electronic Voting Machine with Digital Display

Abstract

This paper presents the design details and implementation of a simple electronic voting machine with a seven segment digital display. The design is based on around the (AT89C52) microcontroller. The work gives all the design details the building blocks of the whole system. The concept design of this prototype is for two voters and an arbitrator. The arbitrator grants permission for voting and each voter can only vote once and protects the identity of the voter to make the process unbiased and fair. The simplicity of this prototype as presented can easily be replicated to cover multiple voters with little overhead in terms of cost.
