single model from pack
It is summer, the sun is shining and a light breeze is blowing. Good that you have a model of a ventilating fan in your construction set. Build the ventilating fan according to the assembly instructions and wire the electrical components. Now you need a new component, which has not yet been explained–the negative temperature coefficient thermistor (NTC).
■ Negative temperature coefficient thermistors are semi-conductor resistors, which are temperature dependent. They have a strong negative temperature coefficient. This is where the name comes from. The resistance value of NTC resistors decreases as the temperature increases, allowing them to conduct electricity better. At decreasing temperature, the resistance increases reducing their conductivity. Since the value of the resistance depends on the temperature, they are not rated. The values can be read off on curves in the data sheets.
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 Ventilating 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.
