Here is the code #include <SoftwareSerial.h> #include <Servo.h> // Define pins const int smokeSensorPin = A0; const int ultrasonicTrigPin = 8; const int ultrasonicEchoPin = 9; const int infraredSensorPin = 7; const int servoPin = 3; const int buzzerPin = 4; // Define variables SoftwareSerial blue…

I have labelled the function of each sensor. @sunjiehao

If this works, please mark my reply as a solution. Thanks
