Use the plot bar chart to visualize the acceleration on the LED screen of the micro:bit in the specified range. You implement forever and plot Bar Graph to constantly display a vertical bar graph, which will be based on the "value" and "high" value.

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.

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 any 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.
