Steps

1. Make sure the components are working properly.
2. Connect the servo motor drive to the Arduino UNO.
3. Connect the Servo motor to their driver circuit.
4. Connect the external power source to the servo motor.
5. Connect the Arduino pin 3&4 to driver circuit.
6. Connect the +5v and ground(gnd) connections respectively.
7. Check the Circuit Connections.
8. Check the Arduino program.
9. Run the Arduino program.

Arduino Program

#include <Stepper.h>
const int stepPin = 3;
const int dirPin = 4;

void setup( )
{
  pinMode(stepPin,OUTPUT);
  pinMode(dirPin,OUTPUT);
}
void loop( )
{
  digitalWrite(dirPin,HIGH);
  for(int x = 0; x < 200; x++)
  {
    digitalWrite(stepPin,HIGH);
    delayMicroseconds(500);
    digitalWrite(stepPin,LOW);
    delayMicroseconds(500);
  }
  delay(1000);
  digitalWrite(dirPin,LOW);
  for(int x = 0; x < 400; x++)
  {
    digitalWrite(stepPin,HIGH);
    delayMicroseconds(500);
    digitalWrite(stepPin,LOW);
    delayMicroseconds(500);    
  }
  delay(1000); 
}
