The flat, black colored line should appear directly beneath the colored line. The black line measures the micro:bit acceleration. And the colored line measures micro:bit simulator acceleration.
A black line should appear directly beneath the colored line. The black line measures the micro:bit acceleration. And the colored line measures micro:bit simulator acceleration.
Run the acceleration experiment by vigarously moving the plate in any direction or move the object below the micro:bit (such as a table).

Second, the flat colored horizontal line will start moving to plot the value of the strength as measured in milli-gravities. The horizontal line's movement is based on the micro:bit acceleration in Magnitude or Strength.

Connect the 2nd micro:bit to your computer using your USB cable. We should have two micro:bit devices attached to the computer.

Click or tap the compile button for the seismograph program to run the program on the 1st micro:bit and 2nd micro:bit.
Use the Recommended Charts command on the Insert tab to quickly create a chart that’s just right for your data.

* Select the data that you want to include in your chart.
The black lines should appear directly beneath the colored lines. The black lines measure the micro:bit acceleration. And the colored lines measures micro:bit simulator acceleration.
* Click Insert > Recommended Charts.

Run the acceleration experiment by vigarously moving the plate in any direction or move the object below the micro:bit (such as a table).
* On the Recommended Charts tab, scroll through the list of chart types that Excel recommends for your data.
Every time the micro:bit moves in any direction, you generate data points that can be reviewed in Excel later. The more attempts to move the micro:bit, the more data to be reviewed in Excel.
Click any chart type to see how your data will look in that format.
When you find the chart type that you want, click it, and then click OK. We want to select the chart called Line. A line chart is used to display trends over time. We will use the line chart because there are many data points over time.
Tip: If you don’t see a chart type that you want, click the All Charts tab to see all of the available chart types.

Have fun reviewing your simulation and analyze the acceleration by chart the Excel data using Excel.
* Connect the first micro:bit to your computer using your USB cable and run the charting script on it.
* Connect the second micro:bit to your computer using your USB cable and run the charting script on it.
* The first person and second person take turns tilting the micro:bit in the "x" direction while the other player charts the data on the micro:bit!
* Have fun reviewing your seismograph data and analyzing the acceleration with Excel.
* The first person and second person take shaking or moving the micor:bit in any direction while the other player charts the data on the micro:bit!
* Review and analyze the actual micro:bit device acceleration data on Excel
* Display acceleration with y or z using plot bar graph by changing acceleration from "x" to "y" or "z"
