Overview of this book

This Learning Path takes you on a journey in the world of robotics and teaches you all that you can achieve with Raspberry Pi and Python. It teaches you to harness the power of Python with the Raspberry Pi 3 and the Raspberry Pi zero to build superlative automation systems that can transform your business. You will learn to create text classifiers, predict sentiment in words, and develop applications with the Tkinter library. Things will get more interesting when you build a human face detection and recognition system and a home automation system in Python, where different appliances are controlled using the Raspberry Pi. With such diverse robotics projects, you'll grasp the basics of robotics and its functions, and understand the integration of robotics with the IoT environment. By the end of this Learning Path, you will have covered everything from configuring a robotic controller, to creating a self-driven robotic vehicle using Python. • Raspberry Pi 3 Cookbook for Python Programmers - Third Edition by Tim Cox, Dr. Steven Lawrence Fernandes • Python Programming with Raspberry Pi by Sai Yamanoor, Srihari Yamanoor • Python Robotics Projects by Prof. Diwakar Vaish

Setting up the MQTT broker


In this topic let's see what we have to do to set up this server. Open up your command line and type in these following lines:

sudo apt-get update
sudo apt-get upgrade

Once the update and upgrade processes are complete, go ahead and install the following packages:

sudo apt-get install mosquitto -y

This will install the Mosquitto broker onto your Raspberry Pi. This broker will take care of all the data transfer:

sudo apt-get install mosquitto-clients -y

Now, this line will install the client packages. As you can imagine, Raspberry Pi in itself will be a client to the broker. Hence, it will take care of the needful.

We have now installed the packages; yes exactly, it was that small. Now, all we need to do is configure the Mosquitto broker. To do this, you need to type in the following command:

sudo nano etc/mosquitto/mosquitto.conf

Now, this command will open the file where the Mosquitto file configuration is saved. To configure it, you need to get to the end of this file...
