The motor driver board contained a ULN2003
This is mainly one of the default examples that comes with the stepper library
Code
#include <Stepper.h>
const int stepsPerRevolution = 512;
// initialize the stepper library on pins 8 through 11:
Stepper myStepper(stepsPerRevolution, 4,5,6,7);
int stepCount = 0;
void setup()
{
// initialize the serial port:
Serial.begin(9600);
}
void loop()
{
myStepper.step(1);
Serial.print(“steps:” );
Serial.println(stepCount);
stepCount++;
delay(500);
}
