I'm new to Arduino and i've been playing with the example sketches. I'm trying out a servo with a potentiometer running the knob example sketch. It works ok except that when i turn the potentiometer fast to the center (position 90) from one end (position 180), the servo will quickly travel to the other end (position 0) and then back to the center position (90). It only does this from 0 to 90, not the other way around (90 to 0). If i turn it slow (normal speed) it won't overshoot.
I came about this problem when i hooked up a joystick(basicely a potentiometer on springs) instead of the potentiometer. When i pulled the stick to one side and let it go the servo would go to the center position, but when i pull the stick to the other side and let it go the servo will travel all the way to the other end and back to the center position again.
I made my circuit like this video
I have an arduino uno. a modelcraft y3009 servo http://shop.conrad.nl/hobby/modelbouw/afstandsbedieningen-en-elektronica/servos/servos/209089.html i used this video tutorial from makezine to make the circuit http://blog.makezine.com/archive/2009/02/how-to-tuesday-arduino-101-potentio.html
Does anyone have any idea how i can prevent this traveling of the servo?
