as the title
i tried using analogWrite()
but failed
tks

btw is sg dc motor tks

Translating is appears to be an ultrasound transceiver. Without the code it is just a wild guess. My first suggestion is to remove the delays.

Welcome to the forum

Arduino code is much easier to deal with if you post it here rather than providing a link to where it is held.

Please post it here using code tags when you do

Which Arduino are you using and what exactly does "failed" mean ?

You don't use analogWrite() with a servo.
What are you trying to do?

bro u are nice
i have another thouhgt by changing the delay to control the speed of motor spin!
thx!

for (pos = 0; pos <= 180; pos += 1) { // goes from 0 degrees to 180 degrees
    // in steps of 1 degree
    myservo.write(pos);              // tell servo to go to position in variable 'pos'
    delay(1/distance);                       // waits depend on distance
  }

thx u for reminding!
the failure means when i make the ultrasound transceiver
and the target distance to 0 ,the motor still move!
(it should not for pwm is 0)
type:uno

i try to adjust the pwm (voltage of motor) in order to change the power of
ball throwing depend on distance detected

Your delay idea should work.
