Nervous servos

Can anyone tip me off why my servos are so "Shaky" ? They are all grounded to eachother(+ the arduino Duo card) Lipo 7,4 connected to the servos and usb powers the Duo.

What type are they? I have

What type are they? I have some cheap HiTec HS-311s that are pretty shaky…

The code would be of help

The code would be of help here … but yes, OddBot pointet it out…maybe it’s just a timing issue or the servos are a cheap Monday production :wink:

at too high voltage the same

at too high voltage the same happened to me here… the servo’s are over-correcting their position. try it at lower voltage.

it sounds like floating

it sounds like floating ground  a copy of code would help or check this out

hope this help

Hi there! Im sorry for not

Hi there! 

Im sorry for not responding, but ive been “too hell and back”. I guess that my code is crap, so i wonder if anyone knows where i can find a working sketch with more than 1 servo, so i can edit it. I only seem to locate the “sweep” code from the arduino.cc site.

Try OddBot’s code on how

Try OddBot’s code on how to drive up to 48 servos.
