Design of Electronic Voting System for Visually Impaired Persons Using Arduino Mega 2560

Abstract

People with visual impairment, even if they are availed to voting, they do not have the privilege to vote confidentially, because of their physical disability. Therefore, a user-friendly and confidential voting system is necessary for visually impaired people. In this paper, we build an electronic voting system for visually impaired people is a user-friendly device which can help those group of people vote independently with sound. The system is built on an Arduino Mega 2560 microcontroller board, a SD card module, an LCD module, several buttons, a buzzer, GSM SIM 900A and a headset. The system has a special voice feature stored in SD card to familiarize them with names of candidates. Also, the voice is passed through a headset for secrecy. In addition, a control unit of the system for polling officials is designed separately from a voting unit for the smooth election procedural. Once user votes, a buzzer is turned on and the system cannot accept the voting. If a control button is pushed, the buzzer is turned off and the system accepts voting. This mechanism is to avoid double voting. A result button is implemented to display final votes for each candidate and store them in the SD card. GSM SIM900A is interfaced with Arduino Mega 2560 to disseminate final results. We can encourage mass participation equally in democracy through the system electronic voting system.
