Stepper Motor Control with LDR

// Stepper Motor Control with Arduino and LDR

// include Arduino stepper motor library
#include <Stepper.h>

// define number of steps per internal motor revolution
#define STEPS 32

// define stepper motor control pins
#define IN1  11
#define IN2  10
#define IN3   9
#define IN4   8

// Create Instance of Stepper Class
// Specify Pins used for motor coils
// The pins used are 8,9,10,11
// Connected to ULN2003 Motor Driver In1, In2, In3, In4
// Pins entered in sequence 1-3-2-4 for proper step sequencing
