🔒 Secure Your Home with a DIY Password-Protected Door Lock!
In this video, I’ll show you how to convert a standard door lock into a password-protected smart lock using Arduino UNO. This easy-to-build DIY electronic lock system uses a 4x4 keypad for password entry, a servo motor to control the locking mechanism, an I2C LCD display for the interface, and a buzzer for security alerts.

💡 How It Works:
✅ Enter the correct password on the 4x4 keypad to unlock the door.
✅ Servo motor acts as the lock actuator, securing or opening the door.
✅ I2C LCD Display provides user feedback on access status.
✅ Buzzer alert sounds for incorrect password attempts.
✅ Fully customizable – you can change the password and upgrade the security!
