IoT and Embedded Systems: Foundations of Hardware and Software

The Internet of Things (IoT) is transforming how we interact with the physical world, bridging the gap between hardware devices and software networks. Understanding how to program these interconnected systems is an essential skill for modern developers, engineers, and tech enthusiasts. This text-only course guides you from the fundamental principles of embedded systems to the practical logic of IoT architecture. You will learn how microcontrollers process data, interface with sensors, and communicate across networks using modern lightweight protocols. Learn how to: - Understand core concepts of embedded hardware, including microcontrollers, memory limits, and input/output interfaces. - Master the fundamentals of writing efficient, low-level code to read sensor data and control physical actuators. - Explore modern IoT communication protocols such as MQTT and CoAP for reliable machine-to-machine data transfer. - Apply basic edge computing principles to process data locally before sending it to the cloud. - Implement essential security practices to protect connected devices from common network vulnerabilities. Starting with foundational definitions of hardware components, the course guides you through structured text lessons covering digital and analog signals, memory management, and wireless networking. You will read through clear code examples and conceptual walkthroughs designed to build your practical understanding step by step. This course is designed entirely for beginners with no prior experience in hardware engineering or embedded programming. Start reading today and take your first step into the world of smart, connected technology.
