This project is an embedded system titled "Password-Based Door Unlocking System". It is designed to enhance security by allowing access only when the correct password is entered. The system is implemented in C++ and is ideal for educational purposes, home automation, and embedded system enthusiasts.
You can watch a demonstration of the system here:

- Password-based authentication for door unlocking
- Simple and user-friendly interface
- Secure access control using microcontroller logic
- Easy to customize the password in code
- Microcontroller (e.g., Arduino, AVR, etc.)
- Keypad for password input
- Servo motor or relay to control door lock
- LCD display (optional, for user feedback)
- Basic electronic components (resistors, wires, breadboard, etc.)
- C++ compiler or Arduino IDE
- Clone this repository:
git clone https://github.com/Mkaify/Password-Based_DoorUnlockingSystem.git
- Open the code in your preferred IDE (e.g., Arduino IDE for Arduino-based systems).
- Connect the hardware components according to your microcontroller’s pin configuration.
- Upload the C++ code to your microcontroller.
- Power up the system.
- Enter the predefined password using the keypad.
- If the password is correct, the door will unlock (servo/relay will activate).
- If the password is incorrect, access will be denied.
- You can change the password by editing the relevant variable in the source code.
- Modify pin assignments as needed to match your hardware setup.
