Develop innovative hardware-based projects in C
The Raspberry Pi has traditionally been programmed using Python. Although this is a very powerful language, many programmers may not be familiar with it. C on the other hand is perhaps the most commonly used programming language and all embedded microcontrollers can be programmed using it.
The C language is taught in most technical colleges and universities and almost all engineering students are familiar with using it with their projects. This book is about using the Raspberry Pi with C to develop a range of hardware-based projects. Two of the most popular C libraries, wiringPi and pigpio are used.
The book starts with an introduction to C and most students and newcomers will find this chapter invaluable. Many projects are provided in the book, including using Wi-Fi and Bluetooth to establish communication with smartphones.
Many sensor and hardware-based projects are included. Both wiringPi and pigpio libraries are used in all projects. Complete program listings are given with full explanations. All projects have been fully tested and work.
The following hardware-based projects are provided in the book:
Using sensors
Using LCDs
I²C and SPI buses
Serial communication
Multitasking
External and timer interrupts
Using Wi-Fi
Webservers
Communicating with smartphones
Using Bluetooth
Sending data to the cloud
Program listings of all Raspberry Pi projects developed in this book are available on the Elektor website. Readers can download and use these programs in their projects. Alternatively, they can customize them to suit their applications.

Computer vision is probably the most exciting branch of image processing, and the number of applications in robotics, automation technology and quality control is constantly increasing. Unfortunately entering this research area is, as yet, not simple.
Those who are interested must first go through a lot of books, publications and software libraries. With this book, however, the first step is easy. The theoretically founded content is understandable and is supplemented by many practical examples. Source code is provided with the specially developed platform-independent open source library IVT in the programming language C/C++. The use of the IVT is not necessary, but it does make for a much easier entry and allows first developments to be quickly produced.
The authorship is made up of research assistants of the chair of Professor Ruediger Dillmann at the Institut für Technische Informatik (ITEC), Universitaet Karlsruhe (TH). Having gained extensive experience in image processing in many research and industrial projects, they are now passing this knowledge on.
Among other subjects, the following are dealt with in the fundamentals section of the book: Lighting, optics, camera technology, transfer standards, camera calibration, image enhancement, segmentation, filters, correlation and stereo vision.
The practical section provides the efficient implementation of the algorithms, followed by many interesting applications such as interior surveillance, bar code scanning, object recognition, 3-D scanning, 3-D tracking, a stereo camera system and much more.
A Combat Guide against E-waste and Throwawayism
This book is for anyone who enjoys tinkering with analog and digital hardware electronics. Regardless of the sophistication of your workspace, only basic tools are required to achieve truly satisfying results. It is intended as a reference guide among other hardware repair publications you may have in your library. However, the book goes a step further than most other repair guides in addressing issues in the modern era of discarded electronics called e-waste.
E-waste should be put to good use. Producing anything new requires not just precious resources and labor, but also energy to make and deliver it to global retail shelves. Your talents and love of electronics can be put to good use by rescuing and resurrecting at least selected units from this endless stream of e-waste. Examples include either restoring through repair, or salvaging reusable electronic and mechanical components for your next project.
Smart tips are provided throughout the book, and much information is tabulated for easy reference. The book expands age-old repair and hacking techniques applied for repair on the workbench into clever methods and applications to achieve effective results with discarded or “non-servicable” electronic consumer products. The final chapter provides real-life examples using all of the previously discussed content in a summarized form for each example repair type.

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?
