I find it funny how I can have close to 1000 components, yet I never seem to have enough parts to make a project. :icon_eek:

The capacitor value depends on what you want the roll-off frequency to be and the value of the resistor that is forming the low-pass filter in conjunction with the capacitor.

F = 1 / (2 * pi * R * C)
