 First, notice that moving the micro:bit in the simulator in any direction, you will change the acceleration value, which is being displayed as the same color as the micro:bit simulator. Also, notice that by moving the micro:bit simulator, there is a changing acceleration value. Second, the flat colored horizontal line will start a waving line to display the value of the strength as measured in milli-gravities. Finally, notice that the LED display will fluctate based on the movement of the micro:bit simulator.
