This circuit integrates various components including an Arduino UNO, an MQ-3 alcohol sensor breakout, a buzzer, a red LED with a resistor, three L298N DC motor drivers, a DC motor, a 12V battery, a rocker switch, and a Neo 6M GPS Module. The Arduino UNO serves as the central microcontroller unit, interfacing with the GPS module for location data, controlling the motor driver for motor operations, reading analog values from the MQ-3 sensor, and managing the LED and buzzer for indication purposes. The circuit is powered by a 12V battery, with voltage regulation provided by the Arduino and motor drivers.
