Lesson 11 adds a Moving Average Filter to the Analog-to-Digital code in Lesson 4.
Turning the potentiometer changes the value read by the Analog-to-Digital converter.
The averaged value is then sent to the LED display. The averaging filter only runs every
0.2 seconds to slow down the display changes and make it visible. The display appears
to count from the old potentiometer position to the new position.
The filter averages the last 8 readings. Choosing a power of two for the number of sam-
ples allows division by simple rotates instead of having to use a true division routine.
Additionally, rather than summing the array every time, it’s faster to keep a running
sum, then subtract out the oldest value in the queue and adding in the new value.
