Overview of this book

This book is designed to introduce you to IoT and Raspberry Pi 3. It will help you create interesting projects, such as setting up a weather station and measuring temperature and humidity using sensors; it will also show you how to send sensor data to cloud for visualization in real-time. Then we shift our focus to leveraging IoT for accomplishing complex tasks, such as facial recognition using the Raspberry Pi camera module, AWS Rekognition, and the AWS S3 service. Furthermore, you will master security aspects by building a security surveillance system to protect your premises from intruders using Raspberry Pi, a camera, motion sensors, and AWS Cloud. We'll also create a real-world project by building a Wi-Fi – controlled robot car with Raspberry Pi using a motor driver circuit, DC motor, and a web application. This book is a must-have as it provides a practical overview of IoT’s existing architectures, communication protocols, and security threats at the software and hardware levels—security being the most important aspect of IoT.

Let's Communicate

In this chapter, we will learn about important communication protocols such as HTTP and MQTT, which are widely used in IoT architecture. We will also introduce you to the JavaScript programming language and understand why it is becoming the choice for developing IoT applications. We will also demonstrate the implementation of protocols using JavaScript and establish communication between Raspberry Pi and the cloud/server programmatically.

The following topics will be covered in this chapter:

  • The internet
  • Rise of JavaScript and Node.js
  • HTTP
  • MQTT
  • MQTT brokers
