Биполярный шаговый двигатель EM-257

Пример из библиотеки Stepper:

/*
Stepper Motor Control - one step at a time

This program drives a unipolar or bipolar stepper motor.
The motor is attached to digital pins 8 - 11 of the Arduino.

The motor will step one step at a time, very slowly. You can use this to
test that you've got the four wires of your stepper wired to the correct
pins. If wired correctly, all steps should be in the same direction.

Use this also to count the number of steps per revolution of your motor,
if you don't know it. Then plug that number into the oneRevolution
example to see if you got it right.

#include <stepper.h>

const int stepsPerRevolution = 200; // change this to fit the number of steps per revolution
// for your motor

// initialize the stepper library on pins 30 through 33:
Stepper myStepper(stepsPerRevolution, 30,31,32,33);

int stepCount = 0; // number of steps the motor has taken

void setup() {
// initialize the serial port:
Serial.begin(115200);
}

void loop() {
// step one step:
for (int i=0; i< 100; i++) {
myStepper.step(1);
delay (20);
}
Serial.print("steps:" );
Serial.println(stepCount);
stepCount++;
delay(500);
}
