pwm - How should I decide the cut-off frequency for my low ...

https://arduino.stackexchange.com/questions/82191/how-should-i-decide-the-cut-off-frequency-for-my-low-pass-filter

The formula assumes that there is no output load, so you should connect an amplifier there. If you are like most folks, you probably have fewer capacitor values on hand than resistor values, so pick the C value first. Let's say it's 1 uFd. Then if you use R=1K the cutoff will be 159 Hz. Change R while listening to the output Share
