Password Door Lock Arduino Project Using Tinkercad

Creating a password-protected door lock using Arduino and simulating it in Tinkercad is a great project to learn about electronics, programming, and digital security. Here's a basic outline of how you could approach this project:
Circuit and Code - drive.google.com/drive/folder...
Tinkercad Simulation Link - www.tinkercad.com/things/bzO8...
Components Needed:
Arduino board (e.g., Arduino Uno)
Servo motor (to actuate the lock)
Keypad (for entering the password)
Jumper wires
Breadboard (optional)
Computer with internet access for using Tinkercad
Steps:
Design the Circuit:
drive.google.com/drive/folder...
Use Tinkercad's circuit editor to design the circuit. Place the Arduino board, servo motor, and keypad on the workspace. Connect them using jumper wires according to the circuit diagram.
Programming:
Write the Arduino code to control the servo motor and keypad.
Use libraries such as Servo.h for controlling the servo motor and Keypad.h for interfacing with the keypad.
Implement the logic for comparing the entered password with the correct password and actuating the servo motor accordingly.
Here's a simplified example of Arduino code:
Simulate in Tinkercad:
Transfer your circuit design and Arduino code to Tinkercad.
Test your simulation by entering different passwords and observing the behavior of the servo motor.
Refinement and Extension:
Once the basic functionality works, consider adding features like:
Allowing the user to change the password.
Implementing multiple user accounts.
Adding indicators (LEDs or LCD) to provide feedback.
Integrating additional security measures.
Documentation and Presentation:
Document your project by explaining the circuit design, code functionality, and any challenges faced.
Present your project, demonstrating how it works and discussing the concepts you've learned.
By following these steps, you can create a password-protected door lock using Arduino and simulate it in Tinkercad. It's a fun and educational project that combines electronics, programming, and digital security concepts.
