Ethan started off by making the basic code for the microbit to read the temperature.
This image is of the code after Ethan added a block that would make a beeping noise when the microbit is at room temperature.
After making the basic code Ethan made an alert system that was designed to play a tone when the temperature is between 18 and 23 degrees.
once this part of the code was completed ethan decided to add another tone but this one was to play when the temperature was below 18 degrees
this is a screen capture of the minor refinements of the code
