## Prior learning/place of lesson in scheme of work
Learn how to get the ambient temperature (degree Celsius °C). The temperature is inferred from the the surface temperature of the various chips on the micro:bit. We will be learning how to get the temperature using on shake, local variables, as well as simple commands such as show number.
