Hello everybody I try to use  this servo https://www.robbe.com/servo-rovor-s0307-37g.html
At arduino but I can't use it with the standard library can someone help me to solve the problem

Oh sure! It's in your wiring, you need to connect the green wire with the purple.

Sorry  I connect the yellow to d9, the brown to ground  and the red to 5v

You didn't say what "the problem" is.

I connect ... the red to 5v
The 5V of what?

The problem ist that nothing happens with the servo with the standard sweep. I connected it with the 5 v pin of the board

If you mean the Arduino's 5V pin then that's at least part of your problem. Try powering the servo from 4 x NiMH AA rechargeable batteries.

If that doesn't do it then post a picture showing your wiring.

But don't forget the grounds...

that's not the solution I the wiring works with a sg90 servo

This site says the sg90 current is 700mA at 5V, which is the same as this site says for the s0307. So if the sg90 works, one would expect the s0307 to work under the same circumstances.

But it's bad practice in any case to use the Arduino as a power supply: did you try with external power?

Perhaps your s0307 is stuffed....

If you won't try external power then it could still be a power problem.

Alternatively you have dead servo or the connections to it are wrong. I have seen servos turn up with the servo connector wired incorrectly.

I test it but It wasn't the solution

I see the problem, actually two.. three.
1. Your orange wire is loose
2. You don't have any power connected
3. You are still trying to power it from arduino's 5V, which was already bad idea. Right?

Cheers,
