potentiometer to control a servo. It works fine when I use the ground and +5 coming from the arduion but everytime I try using the ground and +5 from a different source and running the data pin to the arduino it doesnt seem to work. Any suggestions?

Anytime there are two independent power sources used both their grounds must be wired together, otherwise the control signal does not have a complete circuit through the servo.
