Wow maybe so. The jerky movements might be from a joystick. More research for me.
Murray you were right about the Bluetooth controller. I was able to program two servos and the mini gripper. The servo action is not yet what I want because they are only able to go to a fixed degree instead of infinite control that is available on the joystick,
The joystick are a analog reading. All analog reading get noise, one of the best ways to reduce noise is take 5 reading and use the median reading (the 1 in the middle) i.e sport them into order then use the 3rd reading.
see my video here about analog filtering https://www.youtube.com/watch?v=H51OzQl3BC8
Well done Fixman - glad you’re making progress and seeing the benefits of your efforts.
