For our final project we decided to use the arduino to create a fire
alarm. We used the flame sensor and alarm to create this system, we coded
the device to detect whenever a fire was 40m in range of the build and if
there was a flame the alarm would go off. Our goal was to make this
arduino build consistent but unfortunately the code was really difficult
from day to day since it was constantly changing. Overall it worked and we
could've continued if we had another class by adding the LCD screen to
show when there was fire in range of the sensor.
