I try to use this servo ... At arduino but I can't use it with the standard library can someone help me to solve the problem
I connect ... the red to 5v
You didn't say what "the problem" is.The 5V of what?
Try powering the servo from 4 x NiMH AA rechargeable batteries.
But don't forget the grounds...
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.Steve
that's not the solution I the wiring works with a sg90 servo
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.Steve
