hello guys,
i need to know please what is the reason for a servo to make sounds sometimes and not be sure about it's position ?
especially the blue micro servos
Hi firashelou,
I think we need a few more details, how have you got your servo wired up! a schematic would be useful, and of course your code could be giving the servo the jitters too. So when we see both we can help you a bit more. There are so very cleaver chaps on this forum, and they usually sort me out, once they have something to work on.
Regards
Mel.
Hoi,
it may help by adding a high value capacitor (470uF or greater) between GND and 5V on the breadboard/pcb.
i am sorry to forgot to mention that a capacitor is added to the servo the 470uF
and the servo is wired like every servo it has 3 wires colored brown, red and yellow
brown : GND
Red : +5V
Yellow : Data to arduino
I have many servos tested and can say, the little lightblue micro-servos are junk - the Nylon-gears inside are very soft and, depending on the usage, break after some time.
the black mini-servos are classes better and only 1/4 larger.
the best are the "big" rc-servos - all this is clear because the larger the housing is the better and larger the gears could be

aha well your right because when i try the big black servo no sound ! everything is good
But don't power it from the Arduino like in reply #2, in the first place. Collective wisdom on this forum is that that's a no-no.... even with one servo.

no i am not powering it like that
it is taking power from a voltage regulator, which is taking power from a 12V batteries !

Good, but if that's a 7805 or 06 regulator you'll be wasting half the energy!

aha ok thanks for the info, this will be taken in consideration
Also it should very hot ! 
A.R.Ty:

Fortunately it's not 
nevertheless i connected 2 servos to it, and i put a heat sink
i meant the 7805 - if you "fire" it with 12V is has to be VERY hot without heat sink ! :%

i did put a heat sink attached to it to it
