Story

This is a project that allows the ventilation shaft to be activated automatically if flame is detected using the flame detection sensor. We came up with this project idea because of how it can be used in our daily lives. When cooking food, almost everyone uses the ventilation shaft. This project will automatically turn it on, eliminating the inconvenience in daily life.

#define AIA 9

#define AIB 10

int flame_sensor_pin = 2 ;// initializing pin 7 as the sensor output pin

int flame_pin = HIGH ; // state of sensor

int MTspeed = 50;


void setup ( )  {

 

  pinMode(AIA, OUTPUT);

  pinMode(AIB, OUTPUT);

  pinMode ( flame_sensor_pin , INPUT ); // declaring sensor pin as input pin for Arduino

  Serial.begin ( 9600 );// setting baud rate at 9600

void loop ( ) {

   flame_pin = digitalRead ( flame_sensor_pin ) ;  // reading from the sensor

  if (flame_pin == LOW )  // applying condition
