Summary of the Circuit

This circuit consists of an Arduino UNO microcontroller, an MQ6 gas sensor, and a buzzer. The Arduino UNO serves as the central processing unit, controlling the sensor readings and the buzzer's operation. The MQ6 gas sensor is used to detect the presence of gases in the environment, and the buzzer provides an audible alert. The circuit is designed to monitor gas levels and trigger an alarm when a certain threshold is reached.
