Arduino Fire Alarm

SOURCE CODE:

const int flameSens = A0;//set flame sensor to pin A0 const int speaker = 8;//set speaker to pin 8 int flameVal;//set up the data variable for the sensor

void setup() {

Serial.begin(9600);//begin the serial monitor pinMode(speaker, OUTPUT);//define the speaker as an output pinMode(flameSens, INPUT);//define flame sensor as an input

}

void loop() {

int flameVal = analogRead(flameSens);//read the sensor value of flame sensor

if (flameVal < 1023){//if the data us less than 1023 then set off an alarm tone(speaker, 800, 800); delay(200); tone(speaker, 600, 800); delay(200); } else{ digitalWrite(speaker, LOW);// if else don't set off alarm

}

Serial.println(flameVal);//print the data to the serial monitor }
