Program, build, and master 60+ projects with the Wireless RP2040
The Raspberry Pi Pico and Pico W are based on the fast, efficient, and low-cost dual-core ARM Cortex M0+ RP2040 microcontroller chip running at up to 133 MHz and sporting 264 KB of SRAM and 2 MB of Flash memory. Besides spacious memory, the Pico and Pico W offer many GPIO pins, and popular peripheral interface modules like ADC, SPI, I²C, UART, PWM, timing modules, a hardware debug interface, and an internal temperature sensor.
The Raspberry Pi Pico W additionally includes an on-board Infineon CYW43439 Bluetooth and Wi-Fi chipset. At the time of writing this book, the Bluetooth firmware was not yet available. Wi-Fi is however fully supported at 2.4 GHz using the 802.11b/g/n protocols.
This book is an introduction to using the Raspberry Pi Pico W in conjunction with the MicroPython programming language. The Thonny development environment (IDE) is used in all of the 60+ working and tested projects covering the following topics:
Installing the MicroPython on Raspberry Pi Pico using a Raspberry Pi or a PC
Timer interrupts and external interrupts
Analogue-to-digital converter (ADC) projects
Using the internal temperature sensor and external sensor chips
Using the internal temperature sensor and external temperature sensor chips
Datalogging projects
PWM, UART, I²C, and SPI projects
Using Bluetooth, WiFi, and apps to communicate with smartphones
Digital-to-analogue converter (DAC) projects
All projects are tried & tested. They can be implemented on both the Raspberry Pi Pico and Raspberry Pi Pico W, although the Wi-Fi-based subjects will run on the Pico W only. Basic programming and electronics experience are required to follow the projects. Brief descriptions, block diagrams, detailed circuit diagrams, and full MicroPython program listings are given for all projects.
The Piccolino rapid development board can be used to design microcontroller circuits quickly. The Piccolino has a fast 16f887 PIC microcontroller, voltage regulator, and communications module, and can be easily extended using its four headers.
This e-book contains 30 projects based on the Piccolino. We'll use its unique communications facilities and get the Piccolino to communicate with programs on a PC. On the PC, we use the free programming language Small Basic. You can use this to create Windows programs with buttons and graphs quickly. You will learn how to analyze components such as inductors, capacitors, and OPAMPs, and how to display the measurement results in a graphical format. This will help you to design your circuits easily.
We will then start to adapt to the Piccolino. We'll add components to it to make it more powerful, with extra features such as flow control and digital to analog conversion. The clear instructions will enable you to design and build your adaptations. This way you can make your custom designed Piccolino.
We'll end up making an extension: a PCB that that can be mounted on the Piccolino headers. As an example, we'll design and build an extension for an LCD. You can use the included board layout to make your PCB or have it made for you. At the same time, you will learn how to make your extensions. The only limitation is your imagination!
The clear descriptions along with circuit diagrams and photos, will make the building of these projects an enjoyable experience. Each project has a clear explanation of the reasons why it was designed in a particular way. This helps you learn a lot about the Piccolino, as well as Small Basic, and the components that are used in this e-book. You can adapt the projects to suit your requirements or combine several projects.
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.
1-Wire ist die Bezeichnung für eine serielle Schnittstelle, die mit nur einer Datenader auskommt. Es ist ein Master-Multi-Slave-Kommunikationsprotokoll. Verfügbar sind integrierte Bausteine zur Temperaturmessung, Akkuüberwachung, Echtzeituhr und beispielsweise Hotelschließanlagen. Eine Besonderheit von 1-Wire-Geräten ist die Spannungsversorgung aus der Gegenstation, hierbei erfolgt die Versorgung der Slaves über die Datenleitung.
Der Leser erhält mit „Das 1-Wire-Praxisbuch“ eine umfassende Einführung in die 1-Wire-Technologie. Das Buch zeigt anhand praktischer Projekte zum Nachbauen, wie man verschiedene verfügbare 1-Wire-Chips in eigene Mikrocontroller-gesteuerte Anwendungen integrieren kann, und zwar mit Assembler-Software-Implementierungen für PIC-Mikrocontroller und mit Sketches für den Arduino.
Die 1-Wire-Technik kommt in dem Buch praxisnah bei einem elektronischen Schloss zum Einsatz, das von einem PIC-Mikrocontroller gesteuert wird. Ein weiteres Praxisprojekt erläutert Schritt für Schritt, wie beispielsweise eine ständige Temperaturmessung mit 1-Wire-Bausteinen möglich ist.

Build your textbook weather station or conduct environmental research together with the whole world. With many practical projects for Arduino, Raspberry Pi, NodeMCU, ESP32, and other development boards.
Weather stations have enjoyed great popularity for decades. Every current and even every long discontinued electronics magazine has regularly featured articles on building your own weather station. Over the years, they have become increasingly sophisticated and can now be fully integrated into an automated home — although this often requires loyalty to an (expensive) brand manufacturer across all components.
With your own weather and environmental data, you can keep up and measure things that no commercial station can. It’s also fun: expand your knowledge of electronics, current microcontroller development boards and programming languages in a fun and meaningful way. For less than 10 euros you can get started and record your first environmental data — with time and growing interest, you will continue to expand your system.

Architecture, Programming and Applications
The MSP430 is a popular family of microcontrollers from Texas Instruments. In this book we will work with the smallest type, which is the powerful MSP430G2553. We will look at the capabilities of this microcontroller in detail, as it is well-suited for self-made projects because it is available in a P-DIP20 package.
We will take a closer look at the microcontroller and then build, step by step, some interesting applications, including a 'Hello World' blinking LED and a nice clock application, which can calculate the day of the week based on the date.
You also will learn how to create code for the MSP microcontroller in assembler. In addition to that, we will work with the MSP-Arduino IDE, which makes it quite easy to create fast applications without special in-depth knowledge of the microcontrollers.
All the code used in the book is available for download from the Elektor website.
