Fingerprint Sensor-Based Vehicle Starter Using Arduino

Vehicle security is a growing concern, with traditional key-based ignition systems being susceptible to theft, duplication, and unauthorized access. This paper proposes a biometric-based vehicle ignition system using fingerprint authentication to ensure that only authorized individuals can start the vehicle. The system is developed using an Arduino Uno microcontroller, an R307 fingerprint sensor, five push buttons for fingerprint management, an I2C LCD display, an L298N motor driver, and a DC motor to simulate vehicle ignition. The integration of biometric security eliminates the risk of key duplication and unauthorized use, providing an efficient and secure method of vehicle access. This paper discusses the system’s design, working principle, hardware implementation, and future improvements for real-world applications.
