Introduction to Internet of Things (IoT) with Arduino

Introduction: The Internet of Things (IoT) has revolutionized the way we interact with everyday objects, enabling them to communicate and exchange data over the internet. This article aims to provide a comprehensive overview of IoT, its importance, and how it can be implemented using Arduino. Additionally, we will present a project example along with the list of components required and provide sample codes with detailed explanations.

Project: For this example project, we will create a smart home automation system using Arduino. The objective is to control various home appliances remotely through a web interface. The system will allow users to monitor and control devices such as lights, fans, and door locks from anywhere using their smartphones or computers.
