03  LOVE-O-METER

會依溫度不同而亮一顆燈、兩顆燈、三顆燈(!)

程式碼

 const int sensorPin =A0;
const float baselineTemp = 20.0;
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(" , degree 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);
}


會不斷跑出來現在的溫度~~~~~

04  COLOR  MIXING  LAMP

會依感光不同，LED燈泡產生不同的顏色

程式碼

const int greenLEDPin = 9;

const int redLEDPin = 11;

const int blueLEDPin = 10;

const int redSensorPin = A0;

const int greenSensorPin = A1;

const int blueSensorPin = A2;

int redValue = 0;

int greenValue = 0;

int blueValue = 0;

int redSensorValue = 0;

int greenSensorValue = 0;

int blueSensorValue = 0;

void setup()

{

    Serial.begin(9600);

    pinMode(greenLEDPin,OUTPUT);

    pinMode(redLEDPin,OUTPUT);

    pinMode(blueLEDPin,OUTPUT);

}

void loop()

{

    redSensorValue = analogRead(redSensorPin);

    delay(5);

    greenSensorValue=analogRead(greenSensorPin);

    delay(5);

    blueSensorValue=analogRead(blueSensorPin);

    

    Serial.print("Raw Sensor Values \t Red:");

    Serial.print(redSensorValue);

    Serial.print("\t Green:");

    Serial.print(greenSensorValue);

    Serial.print("\t Blue:");

    Serial.print(blueSensorValue);

    

    redValue=redSensorValue/4;

    greenValue=greenSensorValue/4;

    blueValue=blueSensorValue/4;

    

    Serial.print("Mapped Sensor Values \t Red:");

    Serial.print(redValue);

    Serial.print("\t Green:");

    Serial.print(greenValue);

    Serial.print("\t Blue:");

    Serial.println(blueValue);

    

    analogWrite(redLEDPin,redValue);

    analogWrite(greenLEDPin,greenValue);

    analogWrite(blueLEDPin,blueValue);

}
