使用arduino控制两台电机

Question

使用带有TB6612FNG电机驱动器的arduino来控制两个直流电机。我正在关注此链接http://bildr.org/2012/04/tb6612fng-arduino/我遇到的问题是当我运行下面的代码时电机不运行。如果我发表评论＆＃34;移动（2,255,1）和＃34;然后其中一个电机旋转。为什么两个电机都不会旋转？有什么帮助吗？

//电机A连接在A01和A02之间 //电机B连接在B01和B02之间

int STBY = 10; //standby

//Motor A
int PWMA = 3; //Speed control 
int AIN1 = 9; //Direction
int AIN2 = 8; //Direction

//Motor B
int PWMB = 5; //Speed control
int BIN1 = 11; //Direction
int BIN2 = 12; //Direction

void setup(){
  pinMode(STBY, OUTPUT);

  pinMode(PWMA, OUTPUT);
  pinMode(AIN1, OUTPUT);
  pinMode(AIN2, OUTPUT);

  pinMode(PWMB, OUTPUT);
  pinMode(BIN1, OUTPUT);
  pinMode(BIN2, OUTPUT);
}

void loop(){
  move(1, 255, 1); //motor 1, full speed, left
  move(2, 255, 1); //motor 2, full speed, left


}


void move(int motor, int speed, int direction){
//Move specific motor at speed and direction
//motor: 0 for B 1 for A
//speed: 0 is off, and 255 is full speed
//direction: 0 clockwise, 1 counter-clockwise

  digitalWrite(STBY, HIGH); //disable standby

  boolean inPin1 = LOW;
  boolean inPin2 = HIGH;

  if(direction == 1){
    inPin1 = HIGH;
    inPin2 = LOW;
  }

  if(motor == 1){
    digitalWrite(AIN1, inPin1);
    digitalWrite(AIN2, inPin2);
    analogWrite(PWMA, speed);
  }else{
    digitalWrite(BIN1, inPin1);
    digitalWrite(BIN2, inPin2);
    analogWrite(PWMB, speed);
  }
}

void stop(){
//enable standby  
  digitalWrite(STBY, LOW); 
}
