🔹 What is this project?
This project was part of the **Digital Logic CPRE 281 class**. The goal was to design a **keypad door lock system** using **logic gates and Verilog**.
🔹 Why this project?
Digital locks have been common in my home country since 2002. This project applies **Verilog-based circuit design** to implement a secure locking system.
🛠 Project Description
The keypad lock system includes these main functionalities:
- 🔑 **Unlock** the door when a **4-digit password** is entered.
- 📟 Displays entered digits on **7-segment displays**.
- ❌ Tracks **incorrect attempts** & locks the system if exceeded.
- 🔄 Allows **resetting the password** using a hard reset.
- 🛡 Default password is **1111** after a hard reset.
