In this video, you'll learn how a low-pass filter works and how to implement it on an Arduino to process signals in real-time.
You don't have to be a mathematician to design your low-pass filter. You can use libraries to do the work for you. The python scripts linked below can help you to get started.

Correction(s):
@ 9:28, the Butterworth filter sum should be from 0 to n.
