สเต็ปปิ้งมอเตอร์ ULN2003 Stepper Motor Driver Board + 5V Stepper Motor มีเกียร์ทดรอบแรงบิดสูง

1 x 5 v stepper motor 

#include <Stepper.h>
// Define number of steps per rotation:
const int stepsPerRevolution = 2048;
// Wiring:
// Pin 8 to IN1 on the ULN2003 driver
// Pin 9 to IN2 on the ULN2003 driver
// Pin 10 to IN3 on the ULN2003 driver
// Pin 11 to IN4 on the ULN2003 driver
// Create stepper object called 'myStepper', note the pin order:
Stepper myStepper = Stepper(stepsPerRevolution, 8, 10, 9, 11);
void setup() {
 // Set the speed to 5 rpm:
 myStepper.setSpeed(5);
 
 // Begin Serial communication at a baud rate of 9600:
 Serial.begin(9600);
}
void loop() {
 // Step one revolution in one direction:
 Serial.println("clockwise");
 myStepper.step(stepsPerRevolution);
 delay(500);
 
 // Step one revolution in the other direction:
 Serial.println("counterclockwise");
 myStepper.step(-stepsPerRevolution);
 delay(500);
