If it is not possible to ventilate a bathroom by opening a window, this can be accomplished with a machine. You may be familiar with this from public restrooms, were a fan starts running automatically.
With the ﬁschertechnik bathroom ventilating fan, the fan goes on when the light is switched on. When the light is switched back off, the fan continues to run for a few seconds and then also switches off. The potentiometer allows you to adjust the number of seconds the fan is to continue to run. (0.5sec - 5sec)
Build the model using the assembly instructions and connect the cables according to the circuit diagram.
Part 1 - micro:bit block commands used in the Bathroom Fan Model
