Tempturn of events
It is said that seeing is believing. Build your very own physical temperature gauge (complete with arrows and dashboards) using the servo module.
What Will Happen
The servo motor will rotate according to the input temperature levels from the micro:bit temperature sensor. Using the map function, the range of integer values for the temperature will be scaled proportionately to match the rotation of the servo motor.

Learning Points
- Use in-built micro:bit temperature sensor as input
- Send digital signal to fan module as output
- Program the LED grid to display temperature value
Additional Challenge
As the micro:bit’s on-board temperature is inferred rather than taken from a dedicated component, the temperature may not necessarily be accurate. One way to improve the accuracy is to use an external thermal sensor.
