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.

Controlling the Pi

Previously, we learned how to interface sensors with the Pi, which collects data and transmits it to a server/cloud over the internet. But in this chapter, we will learn how to communicate with the Pi in other ways, that is, to control the Raspberry Pi and devices/actuators connected to it remotely from the cloud over the internet.

As actuators or devices, we take a DC motor and a few LEDs that we want to control remotely.
The hardware requirements for this chapter will be:

  • Raspberry Pi
  • L293D motor driver IC
  • DC motor
  • Two LEDs

Since we have already been working with the Raspberry Pi and know it really well, we will focus on the details of the L293D motor driver, DC motor, and LED.
