Smart Lock -4#shorts#trending#viral#diyprojects #arduinoproject #intamil #basicelectronics

In this video, we build a Password Protected Door Lock System using a TV Remote and Arduino UNO. Instead of a keypad, a normal TV remote is used to enter the password and control the lock mechanism.

This project is perfect for:

✅ Beginners in Arduino
✅ Electronics Students
✅ Engineering College Mini Projects
✅ DIY Enthusiasts
✅ Embedded Systems Learners

📚 Topics Covered:

Arduino UNO Basics
IR Remote Control
IR Receiver
Password Verification System
DC Motor Door Lock Mechanism
L298N Motor Driver
Battery 12v & 7.4v

Remote Button Values Finder Code :https://drive.google.com/file/d/1rQDakkSBPT-piYFV1lR3wdansf2H_aF5/view?usp=drivesdk

Main program :https://drive.google.com/file/d/1Vyfz6aekJcnOHeIE3khH69IG1yxF92AT/view?usp=drivesdk

This project features

✅ Features:

*4-digit IR remote password
*Password LEDs (shows entered digits)
*Backspace button
*Enter button
*Wrong password LED blinking
*Green LED = Unlocked
*Red LED = Locked
*L298N motor control
*Once unlocked, entering the correct *password again will not move the motor
*Motor opens again only after LOCK button is *pressed and the system is locked again
