I've attempted to hook a vex servo module to my arduino with the code provied in the example labled "knob". The actual electric motor just spins and becomes "detached" from the gear. If I rotate the pot(internal to the servo) to the other extreme it works be it keeps turning and the same thing happens.
I opened the servo and measured the Pot. It measured from 2.1k to 114ohms. I looked up the pot(502T) its max is 5k. Is my potentiometer bad causing my servo to keep running to "find" that position either above 2.1k or below 114 ohms? Also, I checked the pot while in the servo circuit.
I also tried to play with my external 10k pot at different extremes. Should I change anything from the example code program because of the vex brand?
