4 驱动方式：

1，采用ARDUINO 的STEPPER库，优点：简单，缺点：阻塞式控制，占用资源大
2，采用AccelStepper库，优点：功能强大，缺点：较复杂
AccelStepper库链接：http://www.airspayce.com/mikem/arduino/AccelStepper/index.html

AccelStepper significantly improves on the standard Arduino Stepper library in several ways:

• Supports acceleration and deceleration
• Supports multiple simultaneous steppers, with independent concurrent stepping on each stepper
• API functions never delay() or block
• Supports 2, 3 and 4 wire steppers, plus 3 and 4 wire half steppers.
• Supports alternate stepping functions to enable support of AFMotor (https://github.com/adafruit/Adafruit-Motor-Shield-library)
• Supports stepper drivers such as the Sparkfun EasyDriver (based on 3967 driver chip)
• Very slow speeds are supported
• Extensive API
• Subclass support

STEPPER库的例程如下：

/*
 Stepper Motor Control - one revolution

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

 The motor should revolve one revolution in one direction, then
 one revolution in the other direction.

#include 

const int stepsPerRevolution = 400;  // change this to fit the number of steps per revolution
// for your motor

// initialize the stepper library on pins 8 through 11:
//Stepper myStepper(stepsPerRevolution, 8, 9, 10, 11);
Stepper myStepper(stepsPerRevolution, 4, 5);

void setup() {
  // set the speed at 60 rpm:
   pinMode(6,OUTPUT); // Enable
  myStepper.setSpeed(2000);
   digitalWrite(6,HIGH); // Set Enable low
  // initialize the serial port:
  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);
  */
}

AccelStepper库的例程如下：

AccelStepper::DRIVER (1) means a stepper driver (with Step and Direction pins).
If an enable line is also needed, call setEnablePin() after construction.

// Shows how to run AccelStepper in the simplest,
// fixed speed mode with no accelerations
