Acknowledgements

This Internet of Things learning resource reflects the contributions of many individuals, organizations, and communities. We are grateful to everyone whose research, teaching, tooling, and feedback have helped shape it.

Students and Teaching Assistants

This textbook has been shaped by hundreds of learners and teaching staff over time. Their questions, project work, and feedback have helped identify concepts that needed clearer explanation, examples that needed updating, and topics that deserved deeper coverage.

Special thanks to the teaching assistants who provided feedback on course materials, helped debug code examples, and contributed insights from working directly with students in labs and office hours.
