Overview of this book

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.

Motor soldering

We saw some basic components of a two-wheel mobile robot. They are the fundamentals of robotics and almost every robot has some of them. In this section, we will go through all the necessary actions you have to do to assemble all the previous components into a working mobile robot.

In the following image, you can see some helpful tools that can make your soldering easier. Obviously, always prefer a soldering station, but the following should do the job. After all, we only have to solder the motors:

The multimeter is useful for measuring the voltages from the motors and sometimes debug our robot. A not-so-good soldering connection may have the result of lower voltage and thus lower RPM in the motor.

Place the soldering iron on the motor and connect the wires. Keeping the soldering iron over the wires for more than 10 seconds may cause the plastic cover of the motor...
