This book is about DC electric motors and their use in Arduino and Raspberry Pi Zero W based projects. The book includes many tested and working projects where each project has the following sub-headings:
Title of the project
Description of the project
Block diagram
Circuit diagram
Project assembly
Complete program listing of the project
Full description of the program
The projects in the book cover the standard DC motors, stepper motors, servo motors, and mobile robots. The book is aimed at students, hobbyists, and anyone else interested in developing microcontroller based projects using the Arduino Uno or the Raspberry Pi Zero W.
One of the nice features of this book is that it gives complete projects for remote control of a mobile robot from a mobile phone, using the Arduino Uno as well as the Raspberry Pi Zero W development boards. These projects are developed using Wi-Fi as well as the Bluetooth connectivity with the mobile phone. Readers should be able to move a robot forward, reverse, turn left, or turn right by sending simple commands from a mobile phone. Full program listings of all the projects as well as the detailed program descriptions are given in the book. Users should be able to use the projects as they are presented, or modify them to suit to their own needs.
The MotoPi is an extension-board to control and use up to 16 PWM-controlled 5 V servo motors. The board can be additional powered by a voltage between 4.8 V and 6 V so a perfect supply is always guaranteed and even larger projects can be powered.
With the additional power supply and the integrated Analog-Digital-Converter, new possibilities can be reached. An additional power supply per motor is not required anymore because all connections (Voltage, Ground, Control) are directly connected to the board.
The control and the programing can be directly done, as usual, on the Raspberry Pi.

The Motorino board is an extension-board to control and use up to 16 PWM-controlled 5V-Servo-motors.
The included clock generator ensures a very precise PWM signal and a very precise positioning.
The board has 2 inputs for voltage from 4.8 V to 6 V which can be used for up to 11 A. With this input, a perfect power supply is always guaranteed and even bigger projects are no problem.
The supply runs directly over the Motorino which provides a connection for voltage, ground and control.
With the build in capacitor, the voltage is buffered which prevents a sudden voltage-drop at a high load. But there is also the possibility to connect another capacitor.
The control and the programing can be done, as usual, with the Arduino. Manuals and code examples allows a quick introduction for beginners.

Secure, Modular, Open-Source and Self-Sufficient
Ever since the Raspberry Pi was introduced, it has been used by enthusiasts to automate their homes. The Raspberry Pi is a powerful computer in a small package, with lots of interfacing options to control various devices. This book shows you how you can automate your home with a Raspberry Pi. You’ll learn how to use various wireless protocols for home automation, such as Bluetooth, 433.92 MHz radio waves, Z-Wave, and Zigbee. Soon you’ll automate your home with Python, Node-RED, and Home Assistant, and you’ll even be able to speak to your home automation system. All this is done securely, with a modular system, completely open-source, without relying on third-party services. You’re in control of your home, and no one else.
At the end of this book, you can install and configure your Raspberry Pi as a highly flexible home automation gateway for protocols of your choice, and link various services with MQTT to make it your own system. This DIY (do it yourself) approach is a bit more laborious than just installing an off-the-shelf home automation system, but in the process, you can learn a lot, and in the end, you know exactly what’s running your house and how to tweak it. This is why you were interested in the Raspberry Pi in the first place, right?
Turn your Raspberry Pi into a reliable gateway for various home automation protocols.
Make your home automation setup reproducible with Docker Compose.
Secure all your network communication with TLS.
Create a video surveillance system for your home.
Automate your home with Python, Node-RED, Home Assistant and AppDaemon.
Securely access your home automation dashboard from remote locations.
Use fully offline voice commands in your own language.

ModbusRTU and ModbusTCP examples with the Arduino Uno and ESP8266
Introduction to PLC programming with OpenPLC, the first fully open source Programmable Logic Controller on the Raspberry Pi, and Modbus examples with Arduino Uno and ESP8266
PLC programming is very common in industry and home automation. This book describes how the Raspberry Pi 4 can be used as a Programmable Logic Controller. Before taking you into the programming, the author starts with the software installation on the Raspberry Pi and the PLC editor on the PC, followed by a description of the hardware.
You'll then find interesting examples in the different programming languages complying with the IEC 61131-3 standard. This manual also explains in detail how to use the PLC editor and how to load and execute the programs on the Raspberry Pi. All IEC languages are explained with examples, starting with LD (Ladder Diagram) over ST (Structured Control Language) to SFC (Special Function Chart). All examples can be downloaded from the author's website.
Networking gets thorough attention too. The Arduino Uno and the ESP8266 are programmed as ModbusRTU or ModbusTCP modules to get access to external peripherals, reading sensors and switching electrical loads. I/O circuits complying with the 24 V industry standard may also be of interest for the reader.
The book ends with an overview of commands for ST and LD. After reading the book, the reader will be able to create his own controllers with the Raspberry Pi.

The Raspberry Pi Build HAT provides four connectors for LEGO Technic motors and sensors from the SPIKE Portfolio. The available sensors include a distance sensor, a color sensor, and a versatile force sensor. The angular motors come in a range of sizes and include integrated encoders that can be queried to find their position.
The Build HAT fits all Raspberry Pi computers with a 40-pin GPIO header, including – with the addition of a ribbon cable or other extension device — Raspberry Pi 400. Connected LEGO Technic devices can easily be controlled in Python, alongside standard Raspberry Pi accessories such as a camera module.
