Circuit Documentation

Summary

This document provides a detailed overview of a circuit that includes an Arduino UNO microcontroller, an MQ6 gas sensor, and a set of resistors. The circuit is designed to interface with the MQ6 sensor for gas detection, with the Arduino UNO serving as the central processing unit. The resistors are used to form voltage dividers or to pull-up/pull-down certain lines.
