Week12上課內容 林佳芳

1.溫度感應
基礎溫度設25度
27左右則亮兩個
30度左右三顆LED亮
程式碼:

const int sensorPin =A0;
const float baselineTemp=25.0;

void setup(){
  Serial.begin(9600);
  for(int pinNumber=2;pinNumber<5;pinNumber++){
    pinMode(pinNumber,OUTPUT);
    digitalWrite(pinNumber,LOW);
  }
}

void loop(){
  int sensorVal=analogRead(sensorPin);
  Serial.print("Sensor Value:");
  Serial.print(sensorVal);

  float voltage=(sensorVal/1024.0)*5.0;
  Serial.print(",Volts:");
  Serial.print(voltage);

  Serial.print(",degrees C:");
  float temperature=(voltage-.5)*100;
  Serial.println(temperature);

  if(temperature<baselineTemp){
    digitalWrite(2,LOW);
    digitalWrite(3,LOW);
    digitalWrite(4,LOW);
  }
  else if(temperature>=baselineTemp+2&& temperature<baselineTemp+4){
      digitalWrite(2,HIGH);
      digitalWrite(3,LOW);
      digitalWrite(4,LOW);
  }
   else if(temperature>=baselineTemp+4&& temperature<baselineTemp+6){
      digitalWrite(2,HIGH);
      digitalWrite(3,HIGH);
      digitalWrite(4,LOW);
  }
   else if(temperature>=baselineTemp+6){
      digitalWrite(2,HIGH);
      digitalWrite(3,HIGH);
      digitalWrite(4,HIGH);
  }
  delay(1);
}

  pinMode(blueLEDPin,OUTPUT);
}

void loop(){
  redSensorValue=analogRead(redSensorPin);
  delay(5);
  greenSensorValue=analogRead(greenSensorPin);
  delay(5);
  blueSensorValue=analogRead(blueSensorPin);

  Serial.print("Mapped Sensor Value \t Red");
  Serial.print(redValue);
  Serial.print("\t Green");
  Serial.print(greenValue);
  Serial.print("\t Blue");
  Serial.print(blueValue);

  analogWrite(redLEDPin,redValue);
  analogWrite(greenLEDPin,greenValue);
  analogWrite(blueLEDPin,blueValue);
}
