arduino代码：

版本一：基本版 - 不使用库

#define in_A_1 2
#define in_A_2 3
#define in_B_1 4
#define in_B_2 5

int currentStep = 0;
 
void setup()
{
    pinMode(in_A_1, OUTPUT);
    pinMode(in_A_2, OUTPUT);
    pinMode(in_B_1, OUTPUT);
    pinMode(in_B_2, OUTPUT);
}
unsigned int time_delay = 200;

void step1(){
    //A+,B+
    digitalWrite(in_A_1, 1);
    digitalWrite(in_A_2, 0);
    digitalWrite(in_B_1, 1);
    digitalWrite(in_B_2, 0);
    delay(time_delay);
}

void step2(){
    //A+,B-
    digitalWrite(in_A_1, 1);
    digitalWrite(in_A_2, 0);
    digitalWrite(in_B_1, 0);
    digitalWrite(in_B_2, 1);
    delay(time_delay);
}

void step3(){
    //A-,B-
    digitalWrite(in_A_1, 0);
    digitalWrite(in_A_2, 1);
    digitalWrite(in_B_1, 0);
    digitalWrite(in_B_2, 1);
    delay(time_delay);
}

void step4(){
    //A-,B+
    digitalWrite(in_A_1, 0);
    digitalWrite(in_A_2, 1);
    digitalWrite(in_B_1, 1);
    digitalWrite(in_B_2, 0);
    delay(time_delay);
}

void tickClock(){
  currentStep++;
  if( currentStep >= 4 ){
    currentStep = 0;
  }
  int cycle = currentStep % 4;
  if( cycle == 0 ){
    step1();
  } else if( cycle == 1 ){
    step2();
  } else if( cycle == 2 ){
    step3();
  } else if( cycle == 3 ){
    step4();
  }
}

void counter_tickClock(){
  currentStep--;
  if( currentStep < 0 ){
    currentStep = 3;
  }
  int cycle = currentStep % 4;
  if( cycle == 0 ){
    step1();
  } else if( cycle == 1 ){
    step2();
  } else if( cycle == 2 ){
    step3();
  } else if( cycle == 3 ){
    step4();
  }
}

void clockwise(long st){
  long i = 0;
  while( i < st ){
    //step1
    step1();
    //step2
    step2();
    //step3
    step3();
    //step4
    step4();
    i++;
  }
}

void counter_clockwise(long st){
  long i = 0;
  while( i < st ){
    //step1
    step1();
    //step4
    step4();
    //step3
    step3();
    //step2
    step2();
    i++;
  }
}
void loop()
{
    //clockwise(18);//counter_clockwise(18);
   // tickClock();
    counter_tickClock();
}

 

 版本二： 调用Stepper库  - 使用arduino Stepper库

#include <Stepper.h>

const int stepsPerRevolution = 48;  // 根据电动机步数更改此值
                                    
Stepper myStepper(stepsPerRevolution, 2,3,4,5);            

int stepCount = 0;         //已经走的步数

void setup() {
  Serial.begin(9600);
}

void loop() {
  if (stepCount < stepsPerRevolution) {  
    myStepper.step(1);
    Serial.print("steps:" );
    Serial.println(stepCount);
    stepCount++;
    delay(500);
  }
}

 

版本三：调用AccelStepper库

#include <AccelStepper.h>

#define HALF4WIRE 8

// Motor pin definitions
#define motorPin1  2     // A1 
#define motorPin2  3     // A2 
#define motorPin3  4     // B1 
#define motorPin4  5     // B2 

// Initialize with pin sequence IN1-IN3-IN2-IN4 for using the AccelStepper with 28BYJ-48
//AccelStepper stepper; // Defaults to AccelStepper::FULL4WIRE (4 pins) on 2, 3, 4, 5

AccelStepper stepper1 (HALF4WIRE, motorPin1, motorPin2, motorPin3, motorPin4, true);

void setup() {
  stepper1.setMaxSpeed(1200.0);
  stepper1.setAcceleration(100.0);
  stepper1.setSpeed(100);
  stepper1.moveTo(12000); //250 full rotations @ 48 steps each = 12,000 steps

}//--(end setup )---

void loop() {

  //Change direction when the stepper reaches the target position
  if (stepper1.distanceToGo() == 0) {
    stepper1.moveTo(-stepper1.currentPosition());
    delay(500);
  }
  stepper1.run();
}
