# SecurePin-KeylessLock

## Project Overview

The SecurePin-KeylessLock is a state-of-the-art digital door lock system developed by Team #5 at PSU, offering a secure and convenient way to manage access to your home or rental property. Designed from scratch, it features a keypad for pin entry, an LCD display for feedback, and a security mechanism to prevent unauthorized access.

## Features

- **Pin Code Access:** Allows users to set and enter a pin code for secure entry.

- **LCD Feedback:** Displays the pin as it's entered and shows messages like "welcome home" or "wrong code".

- **Guess-Proof Security:** Locks out after multiple incorrect attempts and can trigger an alarm.

- **Affordable and Reliable:** Aimed at providing a cost-effective solution without compromising on quality.
