1.LESSON3 溫度感應
程式碼:
const int sensorPin =A0;
const float baselineTemp=26.0;
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(", degress 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);
}
