Hey guys,
So I am really new to this. I have spent the last two days trying to solve my problem, searching all over the web and troubleshooting a bunch of different ways but to no avail.
I am running to 6v servos and whenever they have power supplied to them (2s 7.4v) all they do is click and pulse/vibrate slightly despite the fact they should be moving themselves into a set position. I CAN NOT get them to rotate regardless of what I try.
Any help/guidance or ideas would be greatly appreciated!
What did you try?
Can you post the code? Use code tags.
Can you post a wiring diagram? Pencil, paper and a camera are good enough.
You're running 6V servos on a 2S battery (8.4V fully charged)? What servos are they? There are plenty of servos that will not survive that voltage.
Also if you are expecting them to move to a specific position then you must have some code telling them the position. Please post the code you are using.

Ok! I attached it all for you guys (i hope). For reference, i am using these as my servo's - HERE
Thanks for any help you can provide! (Couldn't figure out how to post my code in here as it exceeded the 9000 character limit to attached it as .txt)

I can't see anything obvious wrong with the code. If your serial prints show you are getting into the various actions then the servos should certainly be doing something.
So that suggests problems with the power and/or wiring. What exactly is the battery you are using? I assume it isn't a 9V PP3 as your picture shows!
Also if the servo power/ground are really connected via a breadboard then that isn't helping. Many breadboards will not support the current needed by that sort of powerful servo on startup. Try connecting the power for the servos directly to the battery. But I'm still not convinced that putting 8.4V into a servo specified for 6.6V is going to be a good idea.

Battery I am using is identical to THIS. Haha not a 9v PP3, just used it in the pic to save time. I rechecked the wiring like 5 times and its all good. Hmmmm, i will give it a go. The battery only puts out around 7v (checked it to be safe) and split between 2 servo's it should be ok. Ill try connecting directly and see how it goes!
A 2S 1900mAh 30C battery is fine. But if it is only showing 7V then it needs charging. Very much lower and you're in danger of damaging it.
