Getting Started with Internet of Things (IoT) using Arduino

Introduction: The Internet of Things (IoT) is a revolutionary concept that connects everyday objects to the internet, allowing them to send and receive data. This technology has the potential to transform various industries, from home automation to industrial monitoring. In this article, we will explore the importance and utility of IoT and provide a detailed example project using Arduino.

Project: For our example project, we will create a smart home monitoring system using Arduino and IoT. The objective is to remotely monitor and control various aspects of a home, such as temperature, humidity, and security. The system will be able to send notifications to the user's smartphone and allow them to control devices remotely.

List of Components:

1. Arduino Uno - 1x
2. DHT11 Temperature and Humidity Sensor - 1x
3. PIR Motion Sensor - 1x
4. ESP8266 Wi-Fi Module - 1x
5. Breadboard - 1x
6. Jumper Wires - Several
7. LED - 1x
8. Resistors - Various values
9. Smartphone with internet connectivity

Examples:

1. Setting up the Arduino and connecting the components:

   • Connect the DHT11 sensor to the Arduino using jumper wires.
   • Connect the PIR motion sensor to the Arduino.
   • Connect the LED to the Arduino for visual notifications.
   • Connect the ESP8266 Wi-Fi module to the Arduino for internet connectivity.

2. Reading temperature and humidity data:
