Bathroom Fan 浴室抽氣扇 (from Electronics Pack)

Model Pack with sensor/input/output

fischertechnik and BBC micro:bit

Product Description

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.
