im trying to control a servo via bluetooth but i get jittering and random inputs through the serial monitor

Post a schematic and your code.

And while you're doing that, to aid with troubleshooting, can you take the BT out of the mix to see if the jittering is related to the BT side of things or not.

Perhaps also clarify what this means:

i get ... random inputs through the serial monitor

I'll take a bit of a wag that this is power related, but in the absence of details, who knows?

Hi,
Welcome to the forum.

Please read the first post in any forum entitled how to use this forum.
http://forum.arduino.cc/index.php/topic,148850.0.html .
Then look down to item #7 about how to post your code.
It will be formatted in a scrolling window that makes it easier to read.

Can you please post a copy of your circuit, in CAD or a picture of a hand drawn circuit in jpg, png?

Thanks.. Tom... :slight_smile:
