Password Based Security System using Arduino Nano | Arduino Project
🔐 *Password Based Security System using Arduino Nano | Arduino Project*
In this video, I have demonstrated a *Password Based Security System* using **Arduino Nano**, a **4x4 Keypad**, **LCD Display**, and a **Buzzer**.
The system allows access only when the correct password is entered through the keypad. If an incorrect password is entered, the system triggers an alert using the buzzer, making it useful for basic security and access control applications.
🔹 *Features:*
Password protected access system
4x4 keypad for password entry
LCD display for user interaction
Buzzer alert for wrong password attempts
Arduino Nano based design
Easy to build and cost-effective
🔧 *Components Used:*
Arduino Nano
4x4 Matrix Keypad
16x2 LCD Display
Buzzer
Resistors
Jumper Wires
Power Supply
📚 *Applications:*
Door security systems
Locker security
Home automation projects
Office access control
School and college science exhibitions
