Try something like this just to test if your electrical setup works.
Code:
#include <Servo.h>
Servo victor1;
void setup(){
victor1.attach(2);
}
void loop(){
victor1.write(180);//0 being full backwards 90 being no motion and 180 being full forwards
}
Last time I used a Victor with an Arduino was about two years ago, I don't have the equipment to test this code right now, but this is essentially what I used to run it.
