Step 5. Step 5.
Notice that making moving the object below the micro:bit changes the values and the line appears as a wave to display the value of the strength as measured in milli-gravities. By making the object below the micro:bit vibrate, you will observe changing values of the micro:bit. Also, the LEDs shown on the Bar Graph fluctates based on the movement of the micro:bit strength. First, notice that making moving the micro:bit simulator in any direction will change the values from a flat horizontal line to a waving line to display the value of the strength as measured in milli-gravities. Next, notice that by moving the micro:bit simulator below, there is a changing acceleration value. Finally, notice that the LED display will fluctate based on the movement of the micro:bit simulator.
NOTE: The black color reflects the micro:bit device.

Vigorously move the micro:bit in the micro:bit simulatator by moving the micro:bit image from side to side. Every time the micro:bit moves in the x direction in the simulator, you are generating data points that can be reviewed in Excel. The more attempts to move the micro:bit from side to side, the more data being saved in Excel. After you have vigarously moved the micro:bit simulator from side to side for a sufficient amount of time, you are ready to graph or chart the accceleration of the micro:bit. We want a printout of our acceleration on Excel that can be graphed in Excel. Vigorously move the micro:bit in the micro:bit simulatator by moving the micro:bit image from side to side.

We want to chart the data collected by using a tool in Excel. * Connect a micro:bit to your computer using your USB cable; compile; and run an acceleration experiment by moving the actual micro:bit.
The final part of this experiment is opening and reviewing the data in the Excel CSV file. Simply click on the line beneath the simulator. A CSV file will be generated to display the data points collected by moving the micro:bit in the X direction. Then click or tap on the data Excel file that was downloaded to your local Downloads Folder. After moving the micro:bit in any direction for several seconds, you can chart acceleration on Excel.

First, notice that by moving the actual micro:bit in any direction, you will change the values of the black, flat horizontal line. The black line will change from being flate to being a waving black line. The changing values of the micro:bit accelereration is being measured in milli-gravities. Next, notice that by moving the micro:bit below, there is a changing acceleration value. Finally, notice that the LED display will fluctate based on the movement of the micro:bit.
