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?

PaulS:
By the way, pin 12 is not a PWM pin.

It is on a Sanguino, which the OP said they are using.
