Arduino Project With Code || Fire Alarm Using Arduino || University Arduino Project for CSE

In this post i’m going to show you “How To Make Fire Alarm Using Arduino”
Tools Procedure:
In the project we will be used a Ardunio UNO R3 Device as a main circuit for fire alarm.
In the project we will be used an alarms, we added a buzzer to the 10th pin of the Arduino.
In the project we will be used a thermostat as a fire sensor for fire alarm circuits.
In the project we will be used a Resistor 10K for fire alarm circuits.
In the project we will be used a small sizes Breadboard for fire alarm circuits.
In the project we will be used some Male to Male Jumper Wires for fire alarm circuits.

Circuit Connection:
Before the connection circuits to computer we need to draw circuit diagram like below:

Code:
float THERMISTORPIN= A0; // Thermistor connected to A0
int buzzerpin = 10;// Buzzer connected to pin 10
void setup(void) {
pinMode(buzzerpin,OUTPUT);
Serial.begin(9600);
}
void loop(void) {
float reading;
reading = analogRead(THERMISTORPIN);
Serial.print(“Analog reading “);
Serial.println(reading);
if (reading<500)
{
digitalWrite(buzzerpin,HIGH);
}
else
{
digitalWrite(buzzerpin,LOW);
}
// convert the value to resistance
delay(1000);
}
