hey guys, so this is my own flame sensor project , im gonna show you guys how it works. This project is very simple to just prove the basics

•

ok guys, 

 

so know im gonna explain you guys how i do this flame sensor project since i think the diagram doesnt look that clear for u guys to see...i dont know why is the software like that.. ok so im gonna move on

 

BUZZER : positive terminal - pin 3

negative terminal - pin GND on the breadboard

LED : positive terminal - pin 7

negative termnial - pin GND

FLAME SENSOR : pin A0 connect to pin A0 on the arduino board

pin GND connect to pin GND on the breadboard

pin + connect to the 5V

 

and then we proceed with the code:

(You guys are welcome to copy the code)

 

#include<SoftwareSerial.h>

 

int sensorPin = A0; // select the input pin for the LDR

 

int sensorValue = 0; // variable to store the value coming from the sensor

 

int led = 9; // Output pin for LED

 

int buzzer = 12; // Output pin for Buzzer

 

void setup() {

 

// declare the ledPin and buzzer as an OUTPUT:

 

pinMode(led, OUTPUT);

 

pinMode(buzzer,OUTPUT);

 

Serial.begin(9600);

 

}

 

void loop()

 

{

 

Serial.println("Welcome to TechPonder Flame Sensor Tutorial");

 

sensorValue = analogRead(sensorPin);

 

Serial.println(sensorValue);

 

if (sensorValue < 100)

 

{

 

Serial.println("Fire Detected");

 

Serial.println("LED on");

 

digitalWrite(led,HIGH);

 

digitalWrite(buzzer,HIGH);

 

delay(1000);

 

}

 

digitalWrite(led,LOW);

 

digitalWrite(buzzer,LOW);

 

delay(sensorValue);

 

}
