The Internet of Things (IoT) is simply the idea of connecting everyday devices to the internet so they can send, receive, and act on data.
From smart lights that turn on when you enter a room to weather stations that upload local temperature and humidity to a cloud dashboard, IoT turns physical things into smart systems.
For students, building IoT projects is one of the best ways to learn electronics, programming, networking, and problem-solving at the same time.
Projects help you see how sensors, microcontrollers, communication modules, and cloud services work together.
They give you practical experience with writing code, wiring hardware, debugging, and documenting results — all skills that are highly valued in school assignments, science fairs, and internships.
