ESP8266 Keypad Password Entry System

Overview

This project demonstrates a password entry system using the ESP8266 microcontroller, a 4x4 keypad, and a buzzer. Users can input a predefined password through the keypad, and the system will provide audio feedback indicating whether the entered password is correct or incorrect.

Features

• 4x4 Keypad Input: Easy password entry via a matrix keypad.
• Password Verification: Checks the entered password against a predefined one.
• Audible Feedback: Provides sound notifications through a buzzer for correct and incorrect password entries.
• Serial Monitor Output: Displays input and verification results on the Serial Monitor for debugging and monitoring.

Components Needed

• ESP8266 microcontroller (e.g., NodeMCU)
• 4x4 matrix keypad
• Buzzer
• Breadboard and jumper wires

Pin Connections
