Design/implement a digital low-pass filter on an Arduino

In this tutorial, 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.
