so that the y-axis is vertical. Press and release your board’s reset button and
walk during the datalogging period. Follow the instructions in Activity #5 for
plotting your datalogged points. You will probably want to graph 200 of the
1001 measurements. Look for a pattern, the graph should exceed some value
and go below some value with each step. Here is an example. Notice that each
step’s acceleration drops below 2900 then exceeds 3300.

Use those values to define the
