De mens is van nature uitgerust met sensoren voor geluid, licht, geur, smaak en gevoel. Zintuigen die met elektronica slechts ten dele gekopieerd kunnen worden. Met de Elektor sensorkit kunnen we wel aardig in de buurt komen. Sensoren kunnen elektronica aansturen, maar ze kunnen ons ook van informatie voorzien. Daarom vormt niet alleen het meten van grootheden, maar ook het zichtbaar maken ervan via de Arduino seriële monitor een niet onbelangrijk deel van dit boek. De microprocessor ATtiny85 die de Arduino-taal begrijpt, maakt het experimenteren met sensoren gemakkelijk en goedkoop. We zullen niet snel een Arduino-kaartje vast solderen in een permanente opstelling. Bij een achtpotige ATtiny zal dat geen schuldgevoel opleveren. Dat neemt niet weg dat alle sketches gewoon op elk Arduino-board draaien met mogelijk hier en daar een aanpassing van pennummers omdat die kunnen verschillen met reguliere Arduino-boards. We zullen uitgebreid aandacht besteden aan het programmeren van de ATtiny. Veel schakelingen zijn bruikbaar in het natuurkundepracticum op school of voor bedrijfsmatige toepassingen. Maar de nadruk ligt toch wel op de (beginnende) elektronicahobbyist die zijn vrije tijd op een leuke maar vooral ook nuttige manier wil besteden. Want meer dan ooit tevoren heeft techniek de toekomst.

An Introduction to RISC-V RISC-V is an Instruction Set Architecture (ISA) that is both free and open. This means that the RISC-V ISA itself does not require a licensing fee, although individual implementations may do so. The RISC-V ISA is curated by a non-profit foundation with no commercial interest in products or services that use it, and it is possible for anyone to submit contributions to the RISC-V specifications. The RISC-V ISA is suitable for applications ranging from embedded microcontrollers to supercomputers. This book will first describe the 32-bit RISC-V ISA, including both the base instruction set as well as the majority of the currently-defined extensions. The book will then describe, in detail, an open-source implementation of the ISA that is intended for embedded control applications. This implementation includes the base instruction set as well as a number of standard extensions. After the description of the CPU design is complete the design is expanded to include memory and some simple I/O. The resulting microcontroller will then be implemented in an affordable FPGA development board (available from Elektor) along with a simple software application so that the reader can investigate the finished design.

STM32 Nucleo family of processors are manufactured by STMicroelectronics. These are low-cost ARM microcontroller development boards. This book is about developing projects using the popular Nucleo development board. In the early chapters of the book, the architecture of the Nucleo family is briefly described. Software development tools that can be used with the Nucleo boards such as the Mbed, Keil MDK, TrueSTUDIO, and the System Workbench are described briefly in later Chapters. The book covers many projects using most features of the STM32 Nucleo development boards where the full software listings for Mbed and System Workbench are given for every project. The projects range from simple flashing LEDs to more complex projects using modules and devices such as GPIO, ADC, DAC, I²C, LCD, analog inputs and others. In addition, several projects are given using the Nucleo Expansion Boards, including popular expansion boards such as solid-state relay, MEMS and environmental sensors, DC motor driver, Wi-Fi, and stepper motor driver. These Expansion Boards plug on top of the Nucleo development boards and simplify the task of project development considerably. Features of this book Learn the architecture of the STM32 microcontrollers Learn how to use the Nucleo development board in projects using Mbed and System Workbench Toolchains Learn how to use the Nucleo Expansion Boards with the Nucleo development boards Update The Mbed compiler has been replaced with two software packages: The Mbed Studio and Keil Studio Cloud. Both of these software packages are free of charge and are available on the Internet. If you need assistance using the Keil Studio Cloud, please download the Guide below.

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.

Analoge schakelingen, sensors en microcontrollers Elektronica is spannend. Het is een hobby die zowel leuk als leerzaam is. Het stelt je in staat om thuis of op het werk nieuwe en nuttige vaardigheden te leren. Een ervaren elektronicus ontwerpt zijn eigen schakelingen, en brengt zijn projecten tot leven. Maar voordat je zover bent, moet je eerst de basis onder de knie krijgen. Daarom brengt dit boek een groot aantal inleidende artikelen samen die in het elektronicatijdschrift Elektor zijn gepubliceerd. Het is je metgezel bij het leerproces in de wereld van de elektronica. Het begint allemaal met analoge elektronica. Je zult de eenvoudigste componenten en circuits ontdekken om te begrijpen hoe ze werken, hoe ze op elkaar inwerken en de mogelijke problemen. De beste manier om vooruitgang te boeken is door echte experimenten uit te voeren, want theorie is niet genoeg. Dit boek begeleid je in een groot aantal praktische projecten voor beginners. Door ze te maken, doe je veel ervaring en kennis op. Het tweede deel van het boek neemt je mee in de wereld van de digitale elektronica. De auteur bespreekt het gebruik van microcontrollers. Taken die voorheen werden uitgevoerd door discrete componenten of conventionele geïntegreerde schakelingen worden nu uitgevoerd door microcontrollers. De programmeertaal BASCOM, maar ook platforms als Arduino, BBC micro:bit en andere, maken dit leerproces veel gemakkelijker. Dit boek beschrijft in detail vele toepassingen van microcontrollers, die betaalbaar zijn voor de beginner. Hier gaan programmeren en solderen hand in hand!
