I working with Arduino Nano Every that has several analog PWM pins. I want to use one to control a small servo.
Do I need to put a resistor between PWM pin and the servo signal?

It depends. In my case I had to add 1k resistor. arduino.stackexchange.com/questions/88609/…zhekaus– zhekaus2022年03月06日 17:37:39 +00:00Commented Mar 6, 2022 at 17:37

No, you don't.
Resistors are used to limit and control current (amongst other things) and you don't need to do that when sending a signal from one digital device to another.
