fischertechnik and BBC micro:bit
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
To achieve fluency and competency in micro:bit coding, you really need to get a thorough understanding of each of the block catagories to be used in the Ventilating Fan Model (see part 2 below for the full code). Fortunately, all the reference guides are available on the BBC micro:bit web site for you to get a deeper and more comprehensive understanding and mastery.
Through this fischertechnik ventilating fan model, you can learn, practise, build fluency and confidence in coding.
The following code has used all the mentioned blocks in Part 1 above.
