Keywords

💡Password

A password is a secret word or phrase that is used for user authentication to prove identity or access approval to systems. In the context of the video, the password is used to secure a door mechanism, and the correct password is required to unlock it. The script mentions entering a password to open the door, indicating its role in the security system of the project.

💡Arduino Nano

The Arduino Nano is a small, affordable, and flexible microcontroller board that is used in electronics projects. It is mentioned in the script as the main controller for the door lock project. The video likely demonstrates how to program the Arduino Nano to manage the door's locking and unlocking based on the password input.

💡Keypad

A keypad is a type of input device that allows users to enter data, usually numbers or characters, through buttons. In the video, a keypad is used for entering the password to unlock the door. It is an essential component of the security system, as it interfaces between the user and the microcontroller to input the password.

💡Servo

A servo is a rotary actuator or linear actuator that allows for precise control of angular or linear position respectively. In the script, a servo is used to physically manipulate the door's lock mechanism. The video probably shows how the servo is connected and programmed to move in response to the correct password being entered.

💡Coding

Coding refers to the process of writing instructions in a computer programming language. The video script mentions coding as a crucial step in setting up the door lock project. It involves writing and uploading a program to the Arduino Nano that defines how the system should respond to password inputs and control the servo.
