ECS MINI PROJECT

Описание: Secure Fingerprint-Based Electronic Voting Machine (EVM) using Arduino
In this video, we build a fully functional biometric Electronic Voting Machine using Arduino, an R307 fingerprint sensor, a 4×4 keypad, and an LCD display. This project shows how fingerprint authentication enhances the security and transparency of voting systems.
