I need a separate supply to drive servos for a robot arm i'm building. i'm using a 10k potentiometer and in the examples they use 5k, i found with the 10k potentiometer the voltage would only change in the lower 1/4 of the potentiometer (hard to select a particular voltage). I swapped out the 220 Ohm resistor recommended and used two 500 ohm resistors in series, now the whole of the potentiometer varies the output voltage.

|two resistors in series|
