Hi, I am trying to drive a motor via PWM, but when I want to turn it off using analogWrite(pin, 0), I can stil hear hum from the motor. If I measure voltage on the PWM pin (nothing attached on it i.e. only uC pin) it reads 0.104V. It makes no change if I set the pin as output or not. How to solve i…

analogWrite(pin, 0) ouputs 0.104V?

What is the value of "pin"?

Have you read this?

BTW, how are you measuring the voltage?
