Building IoT Systems with Arduino, Linux, and App Inventor

Ever wanted to bridge the gap between physical hardware and mobile software? Creating connected devices requires a mix of electronics, operating systems, web development, and mobile programming. This text-only course guides you step-by-step through the fundamentals of building a complete Internet of Things (IoT) ecosystem. You will read clear explanations, study structured code examples, and learn how to link an Arduino microcontroller to a Linux-based server and control it via a custom mobile application. What you'll learn: - Understand foundational electronics concepts and program Arduino microcontrollers using clean, structured code. - Navigate the Linux command line and configure basic server environments. - Build simple web servers using HTML, CSS, and modern lightweight web backend principles. - Create functional mobile applications with App Inventor to interact with your hardware over a network. - Apply secure communication protocols to safely transfer data between your mobile device, server, and Arduino. The journey begins with the absolute basics of hardware and command-line interfaces before moving into web server setup and mobile interface design. Through written tutorials, code walkthroughs, and practical configuration exercises, you will see how all these pieces fit together. This course is designed for absolute beginners with no prior experience in electronics, Linux, or mobile development. Start reading today and build your very first connected hardware project from scratch.
