Elektor Digital Python 3 Programming and GUIs (E-book)
This is the second edition of a book aimed at engineers, scientists, and hobbyists who want to interface PCs with hardware projects using graphical user interfaces. Desktop and web-based applications are covered. The programming language used is Python 3, which is one of the most popular languages around: speed of programming being a key feature. The book has been revised and updated with an emphasis on getting the user to produce practical designs with ease – a text editor is all that is required to produce Python programs. Hardware interfacing is achieved using an Arduino Uno as a remote slave. A full description and source code of the communication interface is given in the book. The slave provides digital and analog input and outputs. Multiple Unos can be included in one project with all control code written in Python and running on a PC One project involves a PIC microcontroller with the code provided that can be loaded into the PIC using the Uno. The web applications and server are all implemented in Python, allowing you to access your electronic hardware over the Internet. The Raspberry Pi computer can be used as your web server. An introductory chapter is provided to get you started with using Linux. The book is written for use with Debian or variations including Mint or Ubuntu. All of the programs in the book are freely available, ready to use and experiment with by way of a download from Elektor.

Elektor Digital FreeCAD for Electronic Applications (E-book)
Practical Introduction to 3D Modeling from Enclosure to Front Panel Embedding a vintage component, creating a professional looking home for a circuit board, or even designing a complex apparatus complete with a chassis – these and many other challenges turn into a stimulating pleasure with FreeCAD. Once you have internalized the basic processes, there are virtually no limits to your imagination. Starting to use a new software is never straightforward – especially with a tool as versatile as FreeCAD. Manageable, but at the same time easily usable individual components provide the starting point in this book. Putting these components together later results in assemblies. In the FreeCAD universe, a workable trajectory is demonstrated. The described procedure is illustrative so the examples are easily applied to custom tasks. The devices were made by the author and illustrated with photos. Creating a 3D design is requiring some effort but the initial investment pays off soon. Besides the impressive spatial representation of the projects, the extracted drawings yield a solid base for documentation and production. Extended FreeCAD capabilities like the unfolding of sheet metal parts enormously add to efficiency and pushes models forward into practical assembly. Soon you will definitely not want to do without FreeCAD!

Elektor Digital Machine Learning with Python for PC, Raspberry Pi, and Maixduino (E-book)
La plupart des gens sont de plus en plus confrontés aux applications de l’intelligence artificielle (IA). Les classements de musique ou de vidéo, les systèmes de navigation, les conseils d'achat, etc. reposent sur des méthodes qui peuvent être attribuées à ce domaine. Le terme intelligence artificielle a été inventé en 1956 lors d’une conférence internationale connue sous le nom de Dartmouth Summer Research Project. Une approche fondamentale consistait à modéliser le fonctionnement du cerveau humain et à construire des systèmes informatiques avancés sur cette base. Bientôt, le fonctionnement de l’esprit humain devrait être clair. Le transférer sur une machine n’était considéré qu’une petite étape. Cette notion s'est avérée un peu trop optimiste. Néanmoins, les progrès de l’IA moderne, ou plutôt de sa sous-spécialité appelée Machine Learning (ML), ne peuvent plus être niés. Dans ce livre, plusieurs systèmes différents seront utilisés pour connaître plus en détail les méthodes d’apprentissage automatique. En plus du PC, le Raspberry Pi et le Maixduino démontreront leurs capacités dans les différents projets. Outre des applications telles que la reconnaissance d'objets et de visages, des systèmes pratiques tels que des détecteurs de bouteilles, des compteurs de personnes ou un « œil qui parle » seront également créés. Ce dernier est capable de décrire acoustiquement des objets ou des visages détectés automatiquement. Par exemple, si un véhicule se trouve dans le champ de vision de la caméra connectée, l'information « Je vois une voiture ! est émis via une parole générée électroniquement. De tels appareils sont des exemples très intéressants de la manière dont, par exemple, les personnes aveugles ou gravement malvoyantes peuvent également bénéficier des systèmes d’IA.

Elektor Publishing Programming Voice-controlled IoT Applications with Alexa and Raspberry Pi
Learn programming for Alexa devices, extend it to smart home devices and control the Raspberry Pi The book is split into two parts: the first part covers creating Alexa skills and the second part, designing Internet of Things and Smart Home devices using a Raspberry Pi. The first chapters describe the process of Alexa communication, opening an Amazon account and creating a skill for free. The operation of an Alexa skill and terminology such as utterances, intents, slots, and conversations are explained. Debugging your code, saving user data between sessions, S3 data storage and Dynamo DB database are discussed. In-skill purchasing, enabling users to buy items for your skill as well as certification and publication is outlined. Creating skills using AWS Lambda and ASK CLI is covered, along with the Visual Studio code editor and local debugging. Also covered is the process of designing skills for visual displays and interactive touch designs using Alexa Presentation Language. The second half of the book starts by creating a Raspberry Pi IoT 'thing' to control a robot from your Alexa device. This covers security issues and methods of sending and receiving MQTT messages between an Alexa device and the Raspberry Pi. Creating a smart home device is described including forming a security profile, linking with Amazon, and writing a Lambda function that gets triggered by an Alexa skill. Device discovery and on/off control is demonstrated. Next, readers discover how to control a smart home Raspberry Pi display from an Alexa skill using Simple Queue Service (SQS) messaging to switch the display on and off or change the color. A node-RED design is discussed from the basic user interface right up to configuring MQTT nodes. MQTT messages sent from a user are displayed on a Raspberry Pi. A chapter discusses sending a proactive notification such as a weather alert from a Raspberry Pi to an Alexa device. The book concludes by explaining how to create Raspberry Pi as a stand-alone Alexa device.

Elektor Digital Develop your own Bluetooth Low Energy Applications (E-book)
For Raspberry Pi, ESP32 and nRF52 with Python, Arduino and Zephyr Bluetooth Low Energy (BLE) radio chips are ubiquitous from Raspberry Pi to light bulbs. BLE is an elaborate technology with a comprehensive specification, but the basics are quite accessible. A progressive and systematic approach will lead you far in mastering this wireless communication technique, which is essential for working in low power scenarios. In this book, you’ll learn how to: Discover BLE devices in the neighborhood by listening to their advertisements. Create your own BLE devices advertising data. Connect to BLE devices such as heart rate monitors and proximity reporters. Create secure connections to BLE devices with encryption and authentication. Understand BLE service and profile specifications and implement them. Reverse engineer a BLE device with a proprietary implementation and control it with your own software. Make your BLE devices use as little power as possible. This book shows you the ropes of BLE programming with Python and the Bleak library on a Raspberry Pi or PC, with C++ and NimBLE-Arduino on Espressif’s ESP32 development boards, and with C on one of the development boards supported by the Zephyr real-time operating system, such as Nordic Semiconductor's nRF52 boards. Starting with a very little amount of theory, you’ll develop code right from the beginning. After you’ve completed this book, you’ll know enough to create your own BLE applications.
