INTRODUCTION TO IOT &                                                                    CHAPTER

                   By the end of this lesson, students will:
                       Define the basics of IoT (Internet of Things) and how devices connect wirelessly.
                       Recognize different wireless methods (Bluetooth, Wi-Fi) and their typical use cases.
                       Set up a Bluetooth module in a block-coding environment to communicate with Arduino.
                       Create a Smartphone-Controlled Lamp project, demonstrating remote control of outputs.





                 So far, you’ve learned to control outputs and read sensor inputs on an Arduino. But modern
                 devices don’t just work alone—they often communicate with apps or networks to share data
                 and receive commands. This is where the Internet of Things (IoT) and wireless communication
                 come in. In this lesson, you’ll discover how to connect an Arduino to a smartphone via Bluetooth,
                 creating a smart lamp that changes colors or turns on/off at your command—no wires attached!




                           WHAT IS IOT AND WHY DOES IT MATTER?


                 DEFINING IOT

                 Internet of Things: A network of “smart” objects—sensors, gadgets, appliances—connected to
                 each other (and sometimes the internet) to share data.

                     Examples:
                     o   Smart home devices (lights, thermostats, security cameras).

                     o   Wearable tech (smartwatches, fitness trackers).

                     o   Industrial automation (factory sensors, remote diagnostics).

                 BENEFITS OF IOT

                     Convenience: Control devices from anywhere (e.g., turning your house lights on while still at
                     work).
