This system presents a novel electronic voting solution tailored for college-level elections, integrating biometric authentication with real-time data transmission. The system is built around an ESP32 microcontroller, a fingerprint sensor for secure user authentication, and an OLED display for interaction. Upon successful authentication, the ESP32 activates Bluetooth to connect seamlessly with an Android application, providing users with a simple interface for voting, polling, or submitting feedback. This system improves security and transparency by ensuring only authorized individuals can vote, while real-time data transmission fosters immediate result processing and accountability. By combining biometric security, ease of use, and instantaneous communication, the system promotes an inclusive and participatory governance environment within educational institutions.
