I'm a beginner with Arduino and I'm trying to use this servo , I use the servo arduino library and I tried the two examples in the arduino IDE but the servo doesn't work
Someone can help me please ???

Well..., the servo has 3 wires, red, brown and orange. What are those wires connected to?

Hi,
Welcome to the forum.

One important thing they neglect in the spec, how much current does it draw.
Can you please post a copy of your circuit, in CAD or a picture of a hand drawn circuit in jpg, png?
Including how you are powering the Arduino and the servo.

Thanks... Tom.. :)
EDIT:Found a YouTube that measures the current under load

Under load 3.17A.
Everything runs on smoke, let the smoke out, it stops running....
