  }
  if (frequency < 0)
    frequency = 0;
  if (frequency > 255)
    frequency = 255;
  return frequency;
}

void setup(){

  pinMode(tcs230_S1, OUTPUT);
  pinMode(tcs230_S2, OUTPUT);
  pinMode(tcs230_S3, OUTPUT);

  Serial.begin(9600);
}

void loop(){
  if (tcs230_Getcolor('R')) {
    Serial.println("RED");

  }
  if (tcs230_Getcolor('B')) {
    Serial.println("BLUE");

  }
  if (tcs230_Getcolor('G')) {
    Serial.println("GREEN");

  }

}

四、效果

识别到红色打印RED,绿色打印GREEN，蓝牙打印BLUE

图中的效果是我测试蓝色的物体
