Specific tutorial examples：

Parking Access Control System Using Arduino: This tutorial outlines the creation of an automated parking access control system using Arduino. The system is designed to manage vehicle entry and exit in parking areas efficiently. It employs an Arduino board, along with other components like an IR sensor, servo motor, and LCD display, to control access. The system detects a vehicle's presence using the IR sensor and then operates the servo motor to lift or lower a barrier, allowing or restricting access. The LCD display provides a user-friendly interface to monitor the system's status. This project is an excellent example of practical Arduino applications in automating and streamlining everyday tasks.

Arduino-Based Gas Leakage Detection: This article presents a project for detecting gas leaks using an Arduino Nano and an MQ5 LPG Gas Sensor. The system is designed to identify gas presence, particularly LPG, in various settings such as homes, hotels, and restaurants. The MQ5 sensor is sensitive to LPG and natural gas, and it alerts users by triggering a red LED and a buzzer in case of gas detection. The project aims to enhance safety by providing an early warning system for gas leaks, which can prevent potential hazards. The tutorial includes a detailed guide on the components required and the steps to build the gas leakage detector.
