Zephyr RTOS Projects for Beginners Hands-On Embedded Systems, Microcontroller Programming, IoT Devices, BLE, Sensors, and Practical Projects by Marcus Tancre Learn how to build real-world embedded systems from the ground up with the Zephyr Real-Time Operating System (RTOS) — a powerful, open-source platform backed by the Linux Foundation. Zephyr RTOS Projects for Beginners is a complete, hands-on guide that walks you through the entire development cycle, from setup and configuration to fully functional IoT prototypes. Whether you’re a beginner, student, or software developer exploring embedded systems, this book provides the clarity and practical depth to help you master Zephyr RTOS through projects that work. You’ll learn how to: • Set up the Zephyr development environment and toolchain • Understand RTOS concepts such as threads, scheduling, and synchronization • Interface LEDs, buttons, and sensors using GPIO and I²C • Manage timers, delays, and interrupts in real-time applications • Implement Bluetooth Low Energy (BLE) communication • Store and retrieve data using Zephyr’s file system and NVS • Debug, profile, and optimize embedded firmware • Design connected IoT systems that interact with the cloud Each chapter builds practical skills and ends with a working project that demonstrates how concepts translate into real applications. Projects Included in This Book: LED Blinking and Button Control – Your first Zephyr application controlling GPIOs. - Task Scheduling Demo – Learn multitasking, thread priorities, and synchronization. - Digital Temperature Sensor Integration – Use I²C to collect and display sensor data. - Data Logger Project – Record and store sensor readings in flash memory. - BLE Beacon Project – Broadcast device data over Bluetooth Low Energy. - IoT Data Logger – Transmit sensor data to a remote cloud dashboard. - Smart Home Controller (Capstone Project) – Combine sensors, BLE, and automation for a connected embedded system. By the end of this book, you’ll have built several fully functional embedded projects, gained a solid understanding of Zephyr RTOS internals, and developed the confidence to create your own IoT and real-time applications. Perfect for: • Beginners in embedded systems • Students and educators in electronics or computer engineering • Software developers transitioning to firmware and IoT • Makers and hobbyists building connected devices
