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.
See The Device Name, Unit & total Prize
Devices | Unit |
Arduino UNO R3 | 1 |
Thermistor (10K) | 1 |
Buzzer | 1 |
Resistor 10K | 1 |
Male to male jumper wires | 4 |
Breadboard | 1 |
Total Cost For Bangladesh About – 600 Taka or 7$ |
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); } |
