Help with camera slider code

Projects Programming
1

I'm attempting to create a simple code for a servo that will attach to a camera slider.

I have a joystick connected and when I press UP or DOWN, the motor will turn but ONLY a little bit. It won't continuously turn.

The servo I'm using is a HiTec Deluxe HS-422

I'm a complete noob.

I tried to change int ServoV_Max = 180; to a higher number and it would rotate further but I can't simply get the motor to go in one direction forever until I release the joystick. Then I'd like it to go in the other direction when I move the joystick in the opposite direction.

Here's my current code:

// letsarduino.com
//  (thumbstick) + Arduino

#include <Servo.h> 

int ServoHorizontalPin = 3;   
int ServoVerticalPin =  4;   
int HorizontalPotPin = A0; 
int VerticalPotPin = A1; 
int ServoH_Min = 0; 
int ServoH_Max = 180;
int ServoV_Min = 0;
int ServoV_Max = 180;

Servo HorizontalServo; 
Servo VerticalServo;   

int HorizontalPotValue;         
int HorizontalServoPosition;   
int VerticalPotValue;         
int VerticalServoPosition;   

void setup()   
{
  HorizontalServo.attach(ServoHorizontalPin);   
  VerticalServo.attach(ServoVerticalPin);         
}

void loop() 
{
  HorizontalPotValue  = analogRead(HorizontalPotPin);
  VerticalPotValue  = analogRead(VerticalPotPin); 
  HorizontalServoPosition  = map(HorizontalPotValue, 0, 1023, ServoH_Min , ServoH_Max);
  VerticalServoPosition  = map(VerticalPotValue, 0, 1023, ServoH_Min , ServoH_Max);   
  HorizontalServo.write(HorizontalServoPosition);       
  VerticalServo.write(VerticalServoPosition);       
  delay(20);   
}

ANY help is appreciated!

You have a servo, not a motor.

There are servos where the control input controls the speed rather than the position. Unfortunately, it does not seem that you have this type of servo.
