C4T free concept simulator
Pi and IoT Concept Concept Simulator
Explore course concepts through adjustable values, prediction, deterministic feedback, and an explanatory trace.
This free concept simulator supports guided prediction, comparison, and reflection. It does not execute code, train models, run databases, create repositories, or replace full project software. The course's always-free pathway also explains how to create project files with freely installable or open tools; paid services and physical hardware remain optional.

Pi and IoT Concept Concept Simulator
Explore course concepts through adjustable values, prediction, deterministic feedback, and an explanatory trace.
Safety note: The GPIO and sensor are simulated. Physical motors require a suitable driver and separate low-voltage power plan.
1 · Predict
Will the modeled controller leave the fan off or turn it on?
2 · Explore
Sample data from the virtual sensor.
The temperature at which the output turns on.
3 · Inspect the result
Ready to simulate
Choose a prediction, adjust the controls, and run the lab. The displayed result comes from the simplified values and rules on this page.
