arduino寻迹小车红外对管代码

以下是Arduino寻迹小车红外对管的代码示例：

//定义左右电机引脚
int leftMotor1 = 5;
int leftMotor2 = 6;
int rightMotor1 = 10;
int rightMotor2 = 9;

//定义左右红外对管引脚
int leftSensor = A0;
int rightSensor = A1;

void setup() {
  //初始化电机引脚
  pinMode(leftMotor1, OUTPUT);
  pinMode(leftMotor2, OUTPUT);
  pinMode(rightMotor1, OUTPUT);
  pinMode(rightMotor2, OUTPUT);
}

void loop() {
  //读取左右红外对管的值
  int leftValue = analogRead(leftSensor);
  int rightValue = analogRead(rightSensor);

  //判断左右红外对管是否在黑线上
  if (leftValue < 500 && rightValue < 500) {
    //左右都在黑线上，直走
    digitalWrite(leftMotor1, HIGH);
    digitalWrite(leftMotor2, LOW);
    digitalWrite(rightMotor1, HIGH);
    digitalWrite(rightMotor2, LOW);
  } else if (leftValue < 500 && rightValue > 500) {
    //左边在黑线上，右边不在，左转
    digitalWrite(leftMotor1, LOW);
    digitalWrite(leftMotor2, HIGH);
    digitalWrite(rightMotor1, HIGH);
    digitalWrite(rightMotor2, LOW);
  } else if (leftValue > 500 && rightValue < 500) {
    //右边在黑线上，左边不在，右转
    digitalWrite(leftMotor1, HIGH);
    digitalWrite(leftMotor2, LOW);
    digitalWrite(rightMotor1, LOW);
    digitalWrite(rightMotor2, HIGH);
  } else {
    //左右都不在黑线上，停止
    digitalWrite(leftMotor1, LOW);
    digitalWrite(leftMotor2, LOW);
    digitalWrite(rightMotor1, LOW);
    digitalWrite(rightMotor2, LOW);
  }
