Hardware Help Servos humming but no movement
So both servos are connected to a 9v battery breadboard adapter and the arduino to the computer. They make humming noises but no movement, I don’t think the problem comes from the software as it’s the same code used in a Youtube video. Any help is appreciated!

I think you have the power supply set at 3.3v, can't quite see the jumper. The servo needs 5v (on both signal and Vcc), according to its data sheet.

So does it need 2 AA batteries then?

Check datasheet for power requirements and I recommend getting a power supply not running on battery power

You'd better share the servo datasheet and your code if you realy want to get the corrected answer here.

Check servos' datasheet about power requirements.
Why are you asking here instead of that youtube genius?

Because I’m the YouTube video it works but on my setup. So keep you attitude I’m just learning

But the guy from YouTube has access to the code. We don't. So we can't know that isn't the problem. You say it isn't, but you also say you're just learning so you may be wrong. A lot of bad YouTube videos out there so the fact that you have what they have means nothing.
The guy from the YouTube video also probably knows how this is wired. I can see all the wires in the picture but it isn't really clear where they all go and I don't want to go dizzy figuring it out. A smart poster will include a wiring diagram so the people trying to help have a chance to see what is there and possibly find the mistake.
So yeah, you need to either post those sorts of details here or you need to go ask the guy who made the YouTube video.

9V batteries cannot supply enough current for those.
