Reversing a potentiometer

[Millenniumman]

I'm using a potentiometer with a DC-DC converter to make an LED flashlight driver. I've got it working pretty well. However, the DC-DC IC produces a higher voltage when the resistance on the potentiometer circuit is lower. This makes sense in general, but it means that the power control potentiometer is backwards, with turning it counterclockwise turning up the juice. This seems like it would be a common problem. Am I missing any easy way of doing this, or inverting the potentiometer somehow? Every volume control in the world must do something about this.

Just reverse the wires to the two ends of the pot.

If you are using two wires to the pot you must move the one outside wire to the other outside pin. If you are using three wires you must swap the two outside wires. In both cases, do not move the centre pin wire.

A typical one turn potentiometer looks like this inside:

One of those moments you just want to hit yourself, I'd wager.
