Servo programming

[Mr.Roboto3335]

I'm having trouble trying to program a servo. Everytime I press the button that should make it rotate it does nothing. Any help would be appreciated.

import edu.wpi.first.wpilibj.Joystick;

public class RobotTemplate extends SimpleRobot {

Servo servo = new Servo(5);
Joystick joystick = new Joystick(1);

/**
* This function is called once each time the robot enters autonomous mode.
*/
public void autonomous() {

}

/**
* This function is called once each time the robot enters operator control.
*/
public void operatorControl() {

if(joystick.getRawButton(3))
{
servo.set(1);
}
else if(joystick.getRawButton(4))
{
servo.set(-1);
}

}

/**
* This function is called once each time the robot enters test mode.
*/
public void test() {

}
}

public void operatorControl() {

if(joystick.getRawButton(3))
{
servo.set(1);
} 
else if(joystick.getRawButton(4))
{
servo.set(-1);
}

}

This should be running in a loop. Like this

while(isOperatorControl()) {
    // Code here
}

You are absolutely correct. I forgot that statement. Servo still won't work. It doesn't even default when I reset the robot. Wiring?

Also, Servo.set() takes a value from 0 to 1, rather then -1 to 1 like a motor.

You can also use code tags to keep your formatting when posting code.

Did you install the servo jumper in the digital sidecar?

No I did not... Found and inserted the jumper and is now working. Thank you!
