Arduino final year projects, NO IOT : Smart Home , Smart parking and Safe lock system.

📘 General Introduction

Welcome to this hands-on Arduino project book, where we explore real-world applications of microcontrollers through three practical and educational projects. Whether you're a student, hobbyist, or DIY enthusiast, this book offers you a solid foundation in Arduino-based electronics and embedded systems.

Each chapter walks you through a unique project that integrates multiple components and sensors:

• Gas Detection and Safety Response System: Uses gas sensors, servos, and an LCD to detect and respond to gas leaks.
• Parking Spot Monitor with Shift Register: Demonstrates how to use a 74HC165 shift register to monitor multiple parking spots using minimal Arduino pins.
• Keypad-Protected Safe Lock: Implements a digital locking mechanism using a 4x4 keypad, LCD, and a servo motor to secure a compartment.

These projects are designed not only to demonstrate individual component usage (like sensors, servos, and LCDs) but also to show how they can work together in more complex, interactive systems. You will learn pin configurations, logical flow, and basic embedded programming techniques, giving you confidence to expand and customize these systems further.

All components are simulated using accessible platforms, and every step is explained clearly, making this book a perfect companion for both learning and tinkering.
