Introduction to the Internet of Things (IoT): Building Connected Systems

The Internet of Things (IoT) is reshaping how we interact with technology, connecting everyday physical devices to the digital world. Understanding how these smart systems communicate is a highly valuable skill for developers, engineers, and tech enthusiasts. This text-based course guides you through the foundational concepts of IoT, helping you transition from a curious beginner to someone who can conceptualize, design, and architect connected device networks. You will explore how sensors, microcontrollers, and cloud databases work together to automate processes and collect actionable data. What you'll learn: - Understand the core architecture of IoT systems, from physical sensors to cloud integration. - Explore modern communication protocols such as MQTT, CoAP, and HTTP/REST for efficient data transfer. - Learn the basics of edge computing and how to process data closer to the source. - Apply essential security best practices to protect connected devices from modern cyber threats. - Analyze how cloud platforms ingest and manage large-scale device data. You will start with key terminology and the physical layer of IoT before moving on to networking, data protocols, and security principles. Through clear written explanations and architectural walk-throughs, you will gain a comprehensive understanding of how to plan and structure your own IoT projects. This course is designed for absolute beginners, aspiring developers, and hardware hobbyists. No prior experience with IoT hardware or programming is required.
