IGCSE Computer Science 0478: Sensors, microprocessors and actuators
Students learn how sensors, microprocessors and actuators work together in a feedback loop to form an automated system, including the 14 syllabus sensors and how to describe a system.
One content description from the full IGCSE Computer Science 0478 — 6.1 Automated Systems journey. All 27 modules below are in that journey too, with the same content — add just these to a class, or the whole strand.
