This is a fire and smoke detector.
This program reads a value on two pins from the arduino.
These pins are: flame and smoke.
Flame and smoke sensors must be connected to these pins.
If flame or smoke is detected, it turns on a red LED, turns off the green LED, activates the alert buzzer and moves the servo motor to a 180 degree position.
If nothing is detected, it turns on the green LED, turns off the red LED and silences the buzzer, and moves a servo motor to the 0 degree position.
Waits 100 milliseconds and resumes scanning.
