Hello guys, hope you are well. In the "fade" example of

arduino IDE we use PWM pins like D9 pin.
But why we use analogwrite() function?
Our connection is in digital ports not analog serial. My question is how could we use analog function in digital ports!

Because it can be considered as a fake analog output and you can get a good analog signal out if you use a lowpass filter
