An embedded system is a specialized computer designed to perform specific tasks. Some embedded systems run without an OS, while others use an OS to enable advanced functionality such as multitasking, networking, real-time processing, and more - essential for complex IoT applications.

Zephyr OS is an open-source real-time operating system designed for modern embedded systems. It offers the scalability and flexibility needed to build efficient, secure, and resource-optimized solutions.

In this talk, we’ll explore the core architecture of Zephyr OS and how it enables developers to build scalable IoT applications, with a practical example using Arduino to demonstrate its integration into real-world projects.
