How to use the SMA library

This library allows you to specify the number of data points to use for the moving average. You can pass the number of data to save to the constructor at the time of instantiation. The default is 10.

#include <SimpleMovingAverage.h>
SimpleMovingAverage avg; // 10
SimpleMovingAverage avg5(5); // 5

Be sure to call the begin function before using it.

avg.begin();

After that you can update the value and get the average by calling update on the instance.

avg.update(10); // 10
avg.update(11); // 10.5
avg.update(12); // 11

You can use the average function if you want to get the current average without updating the value.
