Do I need a resistor to control a servo with a PWM signal? 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?
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.
