On button pressed:
Start an event handler (part of the program that will run when
something happens, like when a button is pressed). This handler works when button A or B
is pressed, or A and B together. When you are using this function in a web browser, click the
buttons on the screen instead of the ones on the micro:bit. In this experiment, when button
A is pressed, show the temperature on micro:bit’s matrix LEDs; when button B is pressed,
show humidity on micro:bit’s matrix LEDs.
