This presentation introduces a fire alarm system built using an Arduino board. It discusses how fire alarm systems save lives and property by reducing damage. The key components needed are a flame sensor, Arduino, breadboard, LED, buzzer, and connecting wires. The flame sensor interfaces with the Arduino to detect flames, and triggers the LED and buzzer which are also connected to the Arduino to alert of a fire. The system is programmed using the Arduino IDE.

3. Introduction to fire alarm system
 Fire alarm systems are perhaps the most
essential elements of any building’s life safety
systems
 Not only do they save countless lives every year,
they often regulate other systems in the building
and property owners
 save huge amounts of money by reducing
damage to their structures

4. Components required
 Flame sensor
 Arduino
 Bread board
 LED
 Buzzer
 Connecting wires

5. Working with components
 Flame sensor interfacing to Arduino
 Flame sensor to Arduino
 vcc -> vcc
 gnd -> gnd
 A0 -> A0

6.  Led interfacing to Arduino
 LED +ve is connected to 9th pin of Arduino
 LED -ve is connected to gnd pin of arduino
 Buzzer interfacing to Arduino
 Buzzer +ve is connected to 12th pin of Arduino
 Buzzer -ve is connected to GND pin of Arduino
 Then we program in arduino ide and set it up in arduino
uno
