FS5109R with arduino

Here is one of my codes, which I tried to use:

// Controlling a servo position using a potentiometer (variable resistor) 
// by Michal Rinott <http://people.interaction-ivrea.it/m.rinott> 

#include <Servo.h> 
 
Servo myservo;  // create servo object to control a servo 
 
 
void setup() 
{ 
  myservo.attach(6);  // attaches the servo on pin 9 to the servo object 
} 
 
void loop() 
{ 
  myservo.write(180);   
}

And wiring is here:

Servo:
Yellow -- Arduino pin 6
Red -- pwr supply 6v +
Black -- pwr supply gnd

Arduino:
pin6 -- Servo
gnd -- pwr supply gnd
usb -- pc
