Fingerprint-Based LED Control System

In this project, I built a fingerprint-based control system using an Arduino Nano and an R308 Biometric Fingerprint Sensor. This device can identify fingerprints and control multiple LEDs, which can be connected to relays, SSRs, or other components for various applications. 🔹 Key Features: ✅ Fingerprint Enrollment & Verification using R308 sensor ✅ Control up to 5 LEDs based on stored fingerprints ✅ Mode Selection via Rocker Switches: Enrollment Mode: Store fingerprints with automatic ID assignment Verification Mode: Identify and activate LEDs based on fingerprints Memory Clear Mode: Erase all stored fingerprints ✅ LED Indicators: Red for enrollment, Green for verification This is a fun and educational project to learn about biometric authentication and security systems. Whether for home automation or access control, you can customize it to fit your needs! 📌 Components Used: 🔹 Arduino Nano 🔹 R308 Fingerprint Sensor 🔹 5 LEDs (device outputs) 🔹 2 LEDs (status indicators) 🔹 2 Rocker Switches 🔹 Resistors & Wires 🔔 Don't forget to Like, Subscribe, and Comment if you found this project useful!
