Het boek “Sensoren aan de Raspberry Pi” richt zich tot iedereen die zich wil verdiepen in een Raspberry Pi in combinatie met Windows 10 IoT Core. Dit besturingssysteem biedt samen met een RPi weliswaar veel rekenkracht, maar voor de communicatie met de buitenwereld zijn nog externe modules en sensoren nodig. Daartoe wordt in dit boek gebruik gemaakt van een sensor-kit met 35 modules die nog geen 60 euro kost. Auteur Florian Schäffer begint zijn boek met de introductie van de Raspberry Pi en hij beschrijft welke hardware u nodig hebt om met de RPi te kunnen werken. Dan volgt een eerste kennismaking met Windows 10 IoT Core. Daarna wordt dieper ingegaan op het gebruik van Visual Studio 2015 en worden de eerste programmeervoorbeelden beschreven. Ook wordt uitgelegd hoe een MySQL-databank kan worden aangestuurd via een app en hoe de als webserver kan worden ingezet. In het tweede deel worden de sensoren stuk voor stuk beschreven met hun eigenschappen en worden er veel toepassingsvoorbeelden gegeven. De source-codes van de programma’s zijn als download bij het boek beschikbaar. Tot slot wordt nog aandacht besteed aan het gebruik van druktoetsen en schakelaars, en het werken met digitale uitgangen en analoge ingangen.

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.

This book discusses the basic components of any alarm system. All alarm systems have two basic functions. First, they monitor their environment looking for a change such as a door or window opening or someone moving about in the room. Second, they alert the legal owner or user to this change. The system described in this book uses a scanning type software to detect intruders. It behaves like a guard dog, pacing up and down the fence line on the lookout for either an intruder or a familiar person. If you have an alarm key, you can disarm the system and enter. With the scanning method, the software is easy to write and explain. It can scan eight alarm zones plus two special fire zones in about one second. You don’t have to be an electrical engineer to install an alarm system, just a decent carpenter, painter, and plasterer! Because this alarm system runs on 12 volts, you don’t have to be a licensed electrician either to install it. The alarm system presented here uses Python software on the Raspberry Pi combined with some elementary electronic circuits. The code described in the book, as well as CAD files and a bill of materials for the alarm panel, are available for free downloading. The book provides the reader with examples of typical configurations coming straight from the author‘s experience. After reviewing the hardware components typically used in common alarm systems, the author shows how to plan one yourself. To implement a modular alarm, no matter if it is for a single house or for a business or restaurant, the book shows how to skillfully combine a Raspberry Pi with small auxiliary electronic circuits. These are not installation instructions but food for thought that will enable readers to find a solution to their needs.

Der Raspberry Pi stellt einen sehr preiswerten, aber doch vollwertigen Computer dar, an den auf einfache Weise verschiedenste Elektronik angeschlossen werden kann. Dieses Buch geht auf eine der Stärken des Raspberry Pi ein: die Kombination von Elektronik und Software. Nach einer kurzen Einführung zum Raspberry Pi wird auf die benötigte Software eingegangen. Im Anschluss wird das Linux-Betriebssystem kurz vorgestellt – gefolgt von einer Einführung in die Programmierung mit Bash, Python und JavaScript. Der Schwerpunkt liegt dabei auf Python. Die Erläuterungen sind in allen Fällen kurz und bündig und trotzdem so ausführlich, dass das Notwendigste besprochen wird, um die folgenden Projekte zu verstehen und individuell anzupassen. Dieses Buch beschreibt 45 spannende und interessante Projekte, wie zum Beispiel ein Wechselblinklicht, eine Motorregelung, Erzeugen und Verarbeiten analoger Signale, ein digitales Thermometer, ein Lichtmesser. Aber auch kompliziertere Projekte wie eine Motor-Geschwindigkeitsregelung, ein Webserver mit CGI (Common Gateway Interface) und Client-Server-Programme werden vorgestellt. Sie können dieses Buch als Projektbuch verwenden und die Projekte nachbauen, um sie dann in der Praxis einzusetzen. Durch die ausführliche Beschreibung mit Schaltplänen und Fotos gestaltet sich der Aufbau auf dem Steckbrett recht einfach. Sie können dieses Buch auch als Lehrbuch verwenden. Bei jedem Projekt wird erklärt, warum es auf diese Art und Weise ausgeführt ist. Sie lernen viel über den Raspberry Pi, Python und die verwendeten Bauteile, so dass Sie selbst die Projekte anpassen, nach eigenen Wünschen erweitern oder mehrere Projekte miteinander kombinieren können. Um Ihnen die Software-Installation zu erleichtern, hat der Autor das Betriebssystem und alle Programmbeispiele auf einer SD-Karte zusammengetragen. Passend zu den Projekten ist neben dieser SD-Karte auch ein Hardware-Starterkit bei Elektor erhältlich.
