Easy DIY Electronic Lock for Beginners!

In this video 🎥, we build a password-protected door lock system using Arduino, a 4×4 keypad, a 16×2 LCD with I2C adapter, and an SG90 servo motor. This DIY project demonstrates how to create a simple electronic lock where you can enter a password to unlock the door and press a button to lock it again 🔑.

💡 What you will learn in this video:

How to connect a 4×4 keypad and LCD screen to Arduino.

How to write Arduino code for password handling.

How to control a servo motor for mechanical door locking.

✨ Why this project is great for beginners:

Easy to build with basic Arduino components.

A fun way to learn about security systems.

Combines hardware, coding, and electronics in one practical project.
