Arduino and Stepper motor pin configuration

I/O Connect to Controller : to pins 8, 10, 9, 11

Use below program  for your stepper motor driver trials
#include <Stepper.h>
#define STEPS 32   
#define STEPSREV 32 * 64  //2048  
Stepper stepper1(STEPS, 8, 10, 9, 11);
int  Steps2Take;
void setup()  
{
}
void loop()
{
  stepper1.setSpeed(1);
  Steps2Take  =  4;  
  stepper1.step(Steps2Take);
  delay(2000);
  Steps2Take  =  STEPSREV / 2;
  stepper1.setSpeed(100);   
  stepper1.step(Steps2Take);
  delay(1000);
 
  Steps2Take  =  + STEPSREV / 2;
  stepper1.setSpeed(700);
  stepper1.step(Steps2Take);
  delay(2000);
  Steps2Take  =  - STEPSREV/ 2;  
  stepper1.setSpeed(700);
  stepper1.step(Steps2Take);
  delay(2000);
}
