Well it could be clearer.
It is not clear if the external supply is grounded to the same point as the arduino.
Put a delay in that loop after the high and low not in between.
What results do you get?

i may need a link to tell me what the delay is. is it a resistor? and i have the pololu ground connected to the ardunio

A delay is an instruction:-
Code: [Select]
delay(100);
Will delay for 0.1 of a second.
You don't show how your pot is wired up.

Ever heard the one about the blind men and the elephant?
The last blind man says "an elephant is soft and mushy".
I find it harder to express logic in English than in Code.
Sometimes an example says more than many times as many words.

i threw the delay in there all it does is bounce i have pin 1 hooked to the 5 volt power pin 2 goes to a 10 ohm resistor which goes to ao pin 3 goes to the ground on the ardunio
