Abstract: A key component of democratic systems is voting, which enables people to voice their opinions and take part in decision-making. However, voter impersonation, repeated voting, ballot tampering, and human mistake while counting are some of the major issues that traditional paper-based voting techniques confront and can jeopardize the integrity of elections. Electronic voting machines, or EVMs, have been introduced to mitigate some of these problems, but they are still susceptible if robust voter verification procedures are not put in place. This project suggests a fingerprint-based biometric smart voting system that uses Arduino to overcome these issues. The method makes sure that every voter is individually identifiable by including fingerprint authentication, which lowers the possibility of fraud and avoids repeated votes. Upon successful verification, voters are able to choose their preferred candidate by utilizing push buttons, with the vote being securely recorded in the Arduino’s memory or on an SD card. Immediate feedback is delivered through an LCD display, LEDs, and a buzzer, which enhances transparency and in user confidence. The system is crafted to be cost-effective, scalable, and appropriate for small-scale elections within institutions such as schools, colleges, and local organizations. Furthermore, it can be expanded for larger applications, incorporating features such as Wi-Fi connectivity, online result transmission, and integration with physical ballot boxes. In summary, the project illustrates a practical, user-friendly, and dependable method for modernizing the voting process, ensuring secure and accurate elections, reducing errors, and fostering voter trust in the electoral system.
