arduino循迹和TCS3200颜色识别小车的代码

以下是基于Arduino的循迹和TCS3200颜色识别小车的代码参考：

循迹小车代码：

//定义引脚
int left1 = 11;
int left2 = 10;
int right1 = 9;
int right2 = 6;
int left_pin = A0;
int right_pin = A1;

//定义阈值
int left_value = 0;
int right_value = 0;

void setup() {
  Serial.begin(9600);
  pinMode(left1, OUTPUT);
  pinMode(left2, OUTPUT);
  pinMode(right1, OUTPUT);
  pinMode(right2, OUTPUT);
}

void loop() {
  //读取左右两个巡线传感器的值
  left_value = analogRead(left_pin);
  right_value = analogRead(right_pin);

  //如果左右都在黑线上，直行
  if (left_value < 600 && right_value < 600) {
    digitalWrite(left1, HIGH);
    digitalWrite(left2, LOW);
    digitalWrite(right1, HIGH);
    digitalWrite(right2, LOW);
  } 
  //如果左侧在黑线上，右转
  else if (left_value >= 600 && right_value < 600) {
    digitalWrite(left1, LOW);
    digitalWrite(left2, LOW);
    digitalWrite(right1, HIGH);
    digitalWrite(right2, LOW);
  } 
  //如果右侧在黑线上，左转
  else if (left_value < 600 && right_value >= 600) {
    digitalWrite(left1, HIGH);
    digitalWrite(left2, LOW);
    digitalWrite(right1, LOW);
    digitalWrite(right2, LOW);
  } 
  //如果左右都不在黑线上，倒车
  else {
    digitalWrite(left1, LOW);
    digitalWrite(left2, HIGH);
    digitalWrite(right1, LOW);
    digitalWrite(right2, HIGH);
  }
}

TCS3200颜色识别小车代码：

//定义引脚
int S0 = 7;
int S1 = 6;
int S2 = 5;
int S3 = 4;
int out_pin = 3;

//定义颜色值
int R = 0;
int G = 0;
int B = 0;

void setup() {
  Serial.begin(9600);
  pinMode(S0, OUTPUT);
  pinMode(S1, OUTPUT);
  pinMode(S2, OUTPUT);
  pinMode(S3, OUTPUT);
  pinMode(out_pin, INPUT);
  digitalWrite(S0, HIGH);
  digitalWrite(S1, LOW);
}

void loop() {
  //读取颜色值
  digitalWrite(S2, LOW);
  digitalWrite(S3, LOW);
  R = pulseIn(out_pin, digitalRead(out_pin) == HIGH ? LOW : HIGH);
  digitalWrite(S2, HIGH);
  digitalWrite(S3, HIGH);
  G = pulseIn(out_pin, digitalRead(out_pin) == HIGH ? LOW : HIGH);
  digitalWrite(S2, LOW);
  digitalWrite(S3, HIGH);
  B = pulseIn(out_pin, digitalRead(out_pin) == HIGH ? LOW : HIGH);

  //判断颜色
  if (R > 200 && G < 100 && B < 100) {
    Serial.println("红色");
  } else if (R < 100 && G > 200 && B < 100) {
    Serial.println("绿色");
  } else if (R < 100 && G < 100 && B > 200) {
    Serial.println("蓝色");
  } else {
    Serial.println("无色");
  }
}

注意事项：

1. 循迹小车需要在黑线上测试阈值，并且根据实际情况调整代码中的阈值。
2. TCS3200颜色识别模块需要根据具体使用的RGB LED颜色，可以在代码中调整阈值或者添加其他颜色的判断。
