The model introduces an analog sensor (thermistor). A step control for a fan is programmed. The rotation of the fan propeller is implemented as a parallel program.
It should take half an hour to set up the fan. The heat measurement should also be completed in the same lesson.
The step control is challenging, so a whole lesson should be scheduled. The programming of the fan rotation is based on the results of model 4 (barrier) and should therefore be easy to solve for the students. The Smart Fan experimental task is more time-consuming due to the temperature measurements. Here, the different measured values could be tabulated together in order to shorten the processing time of the task.
