Affordable solutions with the ESP8266 and 3D printing If you are looking for a small yet powerful IoT device, you are likely to come across the ESP8266 and compatible products on the market today. One of these, the Wemos/Lolin D1 Mini Pro board strikes a remarkable balance between cost and performance. A small and very affordable prototype board, the D1 Mini Pro stands out with its WiFi functionality and a 16-Mbytes flash memory for easy creation of a flash file system. In addition, there are sufficient input and output pins (only one analog input though) to support PWM, I²C, and One-Wire systems to mention but a few. The book describes the operation, modding, construction, and programming of home appliances including a colorful smart home accessory, a refrigerator/greenhouse controller, an AC powerline monitor, a door lock monitor, and an IKEA Trådfri controller. As a benefit, all firmware developed for these DIY, "IoT-ized" devices can be updated over-the-air (OTA). For most of the designs in the book, a small printed circuit board (PCB) and an enclosure are presented so readers can have a finished and attractive-looking product. Readers having – or with access to! – a 3D printer can "print" the suggested enclosures at home or in a shop. Some of the constructions benefit from a Raspberry Pi configured as a gateway or cms server. This is also described in detail with all the necessary configuring. You don’t need to be an expert but the prerequisites to successful replication of the projects include basic skills with PC software including the ability to surf the Internet. In terms of hardware, you should be comfortable with soldering and generally assembling the PCBs presented in the book. All custom software written for the IoT devices, the PCB layouts, and 3D print files described in the book are available for free downloading.

Die Mikrocontrollertechnologie ist eines der wichtigsten Gebiete der modernen Elektronik. Mikrocontroller haben sich in den letzten Jahren in allen Bereichen der modernen Technik etabliert. Der vorliegende Kurs gibt eine umfassende Einführung in die faszinierende Welt der Controllertechnik. Nach grundlegenden Betrachtungen zur Controllertechnologie wird bereits im ersten Teil des Kurses auf die praktische Umsetzung des Stoffes eingegangen. Als Basis dafür dient ein modernes Entwicklungsboard (XMEGA-A3BU Xplained), das mit einem der aktuellsten Controller des Herstellers Atmel ausgestattet ist. Der zweite Teil beschäftigt sich detailliert mit der Programmierung des Controllers. Hier kommt die Sprache „C“ zum Einsatz, da diese in der Firmware-Entwicklung eine dominierende Stellung einnimmt. Die bei weitem überwiegende Mehrheit der professionellen Entwicklungsarbeit wird in C ausgeführt. Diese Programmiersprache bietet eine umfassende Grundlage für alle Controlleranwendungen. Im dritten Teil des Kurses wird schließlich auf die hardwarenahe Programmierung eingegangen. Nach der Durchsprache von Pin-Ansteuerung, Takterzeugung und Oszillatoroptionen werden die anspruchsvolleren Themen wie Interrupts, Timer und Counter, Pulsweitenmodulation und Analog-Digitalwandlung behandelt. Der Kurs setzt auf die Philosophie des „Learning by Doing“. Er eignet sich dadurch hervorragend als praktische Ergänzung für Unterricht und Vorlesungen in Weiterführenden Schulen Technischen Berufsschulen und Fachakademien Fachhochschulen und Universitäten Aber auch der ambitionierte, nichtprofessionelle Anwender kann sich mit dem Lernmaterial einen Überblick über den neuesten Stand der Controllertechnik verschaffen.Umfangreiche Praxisbeispiele und Übungsprogramme runden den Kurs ab und lassen keine Fragen offen.

3rd Edition – Fully updated for Raspberry Pi 4 The Raspberry Pi is a very cheap but complete computer system that allows all sorts of electronics parts and extensions to be connected. This book addresses one of the strongest aspects of the Raspberry Pi: the ability to combine hands-on electronics and programming. Combine hands-on electronics and programming After a short introduction to the Raspberry Pi you proceed with installing the required software. The SD card that can be purchased in conjunction with this book contains everything to get started with the Raspberry Pi. At the side of the (optional) Windows PC, software is used which is free for downloading. The book continues with a concise introduction to the Linux operating system, after which you start programming in Bash, Python 3 and Javascript. Although the emphasis is on Python, the coverage is brief and to the point in all cases – just enabling you to grasp the essence of all projects and start adapting them to your requirements. All set, you can carry on with fun projects. The book is ideal for self-study No fewer than 45 exciting and compelling projects are discussed and elaborated in detail. From a flashing lights to driving an electromotor; from processing and generating analog signals to a lux meter and a temperature control. We also move to more complex projects like a motor speed controller, a web server with CGI, client-server applications and Xwindows programs. Each project has details of the way it got designed that way The process of reading, building, and programming not only provides insight into the Raspberry Pi, Python, and the electronic parts used, but also enables you to modify or extend the projects any way you like. Also, feel free to combine several projects into a larger design.

The Controller Area Network (CAN) was originally developed to be used as a vehicle data bus system in passenger cars. Today, CAN controllers are available from over 20 manufacturers, and CAN is finding applications in other fields, such as medical, aerospace, process control, automation, and so on. This book is written for students, for practising engineers, for hobbyists, and for everyone else who may be interested to learn more about the CAN bus and its applications. The aim of this book is to teach you the basic principles of CAN networks and in addition the development of microcontroller based projects using the CAN bus. In summary, this book enables the reader to: Learn the theory of the CAN bus used in automotive industry Learn the principles, operation, and programming of microcontrollers Design complete microcontroller based projects using the C language Develop complete real CAN bus projects using microcontrollers Learn the principles of OBD systems used to debug vehicle electronics You will learn how to design microcontroller based CAN bus nodes, build a CAN bus, develop high-level programs, and then exchange data in real-time over the bus. You will also learn how to build microcontroller hardware and interface it to LEDs, LCDs, and A/D converters. The book assumes that the reader has some knowledge on basic electronics. Knowledge of the C programming language will be useful in later chapters of the book, and familiarity with at least one member of the PIC series of microcontrollers will be an advantage, especially if the reader intends to develop microcontroller based projects using the CAN bus.

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.
