# Arduino Password Validator

----------

## Overview

This project is an Arduino-based password validator. It uses a keypad for input, a buzzer for incorrect password alerts, and an LED to indicate when the correct password is entered. The user inputs a password using the keypad; if the password is correct, the LED will light up. If the password is incorrect, the buzzer will sound.
