arduino控制三电机简单运动

涛123

求大神帮助一下
程序思路：有三个电机123，先让1动，然后23动，再让1动，再让23动。
问题：只有2.3电机动
代码：

#define PUL1 9

#define PUL 7

#define PUL2 5

#define DIR1 8

#define DIR 6

#define DIR2 4

void setup()

{

  pinMode(PUL1,OUTPUT);                                                                                    

  pinMode(PUL, OUTPUT);

  pinMode(PUL2, OUTPUT);

  pinMode(DIR1, OUTPUT);

  pinMode(DIR, OUTPUT);

  pinMode(DIR2, OUTPUT);

  Serial.begin(9600);

}

void loop()

{

digitalWrite(DIR2,LOW);

for(int x=0;x<6000;x++);

{

digitalWrite(PUL2,HIGH);

delayMicroseconds(500);

digitalWrite(PUL2,LOW);

delayMicroseconds(500);

}

delay(1000);

  digitalWrite(DIR1, HIGH);

  digitalWrite(DIR, LOW);

  for (int x = 0; x < 2000; x ++)         // 正向转X圈（2000脉冲）

{

    digitalWrite(PUL1, HIGH);

    digitalWrite(PUL, HIGH);

    delayMicroseconds(500);

    digitalWrite(PUL1, LOW);

    digitalWrite(PUL, LOW);

    delayMicroseconds(500);

  }

  delay(1000); // Delay for one second

digitalWrite(DIR2,HIGH);

for(int x=0;x<6000;x++);

{

digitalWrite(PUL2,HIGH);

delayMicroseconds(500);

digitalWrite(PUL2,LOW);

delayMicroseconds(500);

}

delay(1000);

  // Changes the rotation direction or rotates in opposite direction

  digitalWrite(DIR1, LOW);

  digitalWrite(DIR, HIGH);

  for (int x = 0; x < 6000; x ++)          // 反向转X圈（6000脉冲）

{

    digitalWrite(PUL1, HIGH);

    digitalWrite(PUL, HIGH);

    delayMicroseconds(500);       

    digitalWrite(PUL1, LOW);

    digitalWrite(PUL, LOW);

    delayMicroseconds(500);

}

  delay(2000);     //Delay for 2 seconds

}
