Raspberry Pi Zero W Wireless Projects

IoT and Networking

In the previous chapter, we introduced the new Raspberry Pi Zero W board. We also mentioned several accessories that someone could buy with the board to make their life easier without struggling to connect everything together. Before developing a project with that board, there is something that must be mentioned and analyzed from different perspectives. Since Raspberry Pi Zero W will be connected to the internet, it's time to talk about Internet of Things and networking. In this chapter, we will go through the following topics:

  • Internet of Things
  • Basic communication protocols
  • Pi Zero setup
  • Router setup
  • Network administration
  • Security

Internet of Things

Two words hiding a new world. In a few years from now, every thing and every device you own will be connected to the internet. With the new era of IoT, a huge amount of data will be collected for input on artificially intelligent algorithms or systems. Imagine if your toaster is equipped with sensors, and know what kind of bread you are using, what time you activate it, and how many times per day you want to eat toast. This information may be useless for you, but for the big companies out there willing to spend billions and risk everything on how many toasts they should produce, it is not just something, it's a game changer. So, the Internet of Things is all the things that are connected to the internet such as your computer, your lights, your fridge, your garage door, and anything else that you are able to access through the internet.

On the other side...

Basic communication protocols

Let's assume that we have a Raspberry Pi as our client and https://www.facebook.com as our server. When our client requests a web page from the server there must be some protocols, some rules that this request will be handled. With other words, there must be a specific way of transmitting and receiving data from each other. Internet Protocols (IP) are exactly the rules according to which a client and a server talk.

There are some basic IP with which the current browsers communicate with servers and get data. However, when we talk about IoT and low power hardware, we cannot keep these protocols and use them. As a result, it is important to go through some basic stuff and know the idea behind all the communications out there.

Internet protocols

...

Connecting your Pi

At this point, we have to connect the Raspberry Pi Zero W to the internet. To do this, we first have to understand how internet works. How everything's connected and how we will manage to plug in our Raspberry Pi. This section of the book will demonstrate how to guide for a variety of routers. Since every process is different, I will try to describe the basic idea here and hopefully you will be able to find your solution.

Pi Zero W setup

Firstly, in order to follow the rest of the book, you have to connect your Raspberry Pi zero to a monitor using HDMI and then do the following. Create a new folder with the name ssh at /boot folder and restart your pi. You will be prompted with a message about SSH....

Connecting for file transfer

Sometimes, we are against the problem of transferring data and files at and from our Raspberry Pi. SSH cannot be used for that, so the following section will describe ways that you can easily transfer files from and to your raspberry pi.

FileZilla

FileZilla software can be downloaded on either Windows or Linux and it is pretty simple. For Windows you can download it from https://filezilla-project.org/download.php and for Linux you can use the same link or type the following command:

sudo apt-get install filezilla

After installing this software, all you have to do is type the IP address of the Raspberry Pi, the port (which be default is 22), and the username/password which usually are pi/raspberry...

Secure the Raspberry Pi and remove others

In the last section of this chapter, we will talk about security. Raspberry Pi Zero W is great but no one wants to just plug it in your router and let others control your lights, your coffee machine, and anything else you have connected there. To begin with, the truth is that you cannot be secure from anyone. This means that there are levels of security that you should consider. At this point, you should consider from whom you want to be secured. For example, there are techniques for securing your Raspberry from your family, from your friends, from anyone in your house, from typical users on the internet, from advance users on the internet, and from NSA.

Firewall

Almost every router...

Summary

In this chapter, we went through some basics of networking, and saw how you can connect your Raspberry Pi over the network. We also talked about getting access over the internet, and about IoT protocols.

In the next chapter, we will start building our first project with the new Raspberry Pi Zero W board and look at more practical things using all the knowledge from the previous chapters.

Key benefits

  • Explore the functionalities of the Raspberry Pi Zero W with exciting projects
  • Master the wireless features (and extend the use cases) of this $10 chip
  • A project-based guide that will teach you to build simple yet exciting projects using the Raspberry Pi Zero W board

Description

The Raspberry Pi has always been the go–to, lightweight ARM-based computer. The recent launch of the Pi Zero W has not disappointed its audience with its $10 release. "W" here stands for Wireless, denoting that the Raspberry Pi is solely focused on the recent trends for wireless tools and the relevant use cases. This is where our book—Raspberry Pi Zero W Wireless Projects—comes into its own. Each chapter will help you design and build a few DIY projects using the Raspberry Pi Zero W board. First, you will learn how to create a wireless decentralized chat service (client-client) using the Raspberry Pi's features?. Then you will make a simple two-wheel mobile robot and control it via your Android device over your local Wi-Fi network. Further, you will use the board to design a home bot that can be connected to plenty of devices in your home. The next two projects build a simple web streaming security layer using a web camera and portable speakers that will adjust the playlist according to your mood. You will also build a home server to host files and websites using the board. Towards the end, you will create free Alexa voice recognition software and an FPV Pi Camera, which can be used to monitor a system, watch a movie, spy on something, remotely control a drone, and more. By the end of this book, you will have developed the skills required to build exciting and complex projects with Raspberry Pi Zero W.

Who is this book for?

If you are a hobbyist or an enthusiast and want to get your hands on the latest Raspberry Pi Zero W to build exciting wireless projects, then this book is for you. Some prior programming knowledge, with some experience in electronics, would be useful.

What is custom duty/charge? Chevron down icon Chevron up icon

Customs duty are charges levied on goods when they cross international borders. It is a tax that is imposed on imported goods. These duties are charged by special authorities and bodies created by local governments and are meant to protect local industries, economies, and businesses.

Do I have to pay customs charges for the print book order? Chevron down icon Chevron up icon

The orders shipped to the countries that are listed under EU27 will not bear custom charges. They are paid by Packt as part of the order.

List of EU27 countries: www.gov.uk/eu-eea:

A custom duty or localized taxes may be applicable on the shipment and would be charged by the recipient country outside of the EU27 which should be paid by the customer and these duties are not included in the shipping charges been charged on the order.

How do I know my custom duty charges? Chevron down icon Chevron up icon

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

For example:

  • If you live in Mexico, and the declared value of your ordered items is over $ 50, for you to receive a package, you will have to pay additional import tax of 19% which will be $ 9.50 to the courier service.
  • Whereas if you live in Turkey, and the declared value of your ordered items is over € 22, for you to receive a package, you will have to pay additional import tax of 18% which will be € 3.96 to the courier service.
