How to Make Fingerprint Door Lock | Arduino Project

In this video, we'll show you how to create a fingerprint-based door lock system using Arduino and a 16x2 LCD display. This project enhances home security by allowing access only to authorized fingerprints. We'll guide you through the setup, wiring, and coding needed to integrate a fingerprint sensor with an LCD display for real-time feedback.
