We will measure `acceleration (mg)` in terms of strength or Magnitude. Get the acceleration value (milli g-force), as measured in strength or Magnitude.

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. Then measure the acceleration based on the strength or Magnitude.
Use the plot bar chart to visualize the acceleration on the LED screen. Use a forever to keep reading the acceleration value and displaying it on the screen.

Finally, we subtract the gravity from acceleration strength.
At rest, the micro:bit is always subject to Earth gravity, whose magnitude is measured around ``1023``. Substract ``1023`` to measure a data close to ``0``.
