Automatic fire extinguisher

Hey everyone. Are you afraid of fire. From ancient times we have thought to eradicate the dangers of fire. So to remove our fear of fire lets make automatic fire extinguisher.

Connections:

Digital pin of flame sensor to 8 pin of arduino

Gnd to gnd

Vcc to 5v

black pin of dc water pump to negative of battery.

red pin of dc water pump to common of relay

normally open pin of relay to positive of dc water pump

signal pin of relay to 7 of arduino

gnd to gnd

vcc to 5V

signal pin of servo to 10 OF ARDUINO

GND TO GND

VCC to 5V

Code

#include <Servo.h>

Servo myservo;

void setup() {

// put your setupcode here, to run once:

pinMode(8, INPUT);

myservo.attach(10);

pinMode(7, OUTPUT);

}

void loop() {

// put your maincode here, to run repeatedly:

if(digitalRead(8)==HIGH)

{myservo.write(0);

digitalWrite(7, HIGH);

}

else{

myservo.write(360);

myservo.write(0);

digitalWrite(7, LOW);

}

}

Non technical requirements:

Attach flame sensor on servo motor

Attach dc water pump to servo motor

Precautions:

Make sure when servo motor rotates the wiring of flame sensor doesn’t disturb.
