Run the acceleration experiment by vigarously moving the plate in any direction or move the object below the micro:bit (such as a table).
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.

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. Notice that the LED on the 2nd micro:bit changes to communicate the movement of the 1st micro:bit.

Now we are ready to graph or chart the accceleration of the micro:bit. We want a printout of the micro:bit acceleration graphed in Excel.
## 10.
In order to receive the the data plotted by Excel, click or tap anywhere in the on the chart data.

* Have fun reviewing your seismograph data and analyzing the acceleration with Excel.
