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.

Projects with Thonny-IDE, uPyCraft-IDE, and ESP32 The 'Python' programming language has enjoyed an enormous upswing in recent years. Not least, various single-board systems such as the Raspberry Pi have contributed to its popularity. But Python has also found widespread use in other fields, such as artificial intelligence (AI) or machine learning (ML). It is obvious, therefore, to use Python or the 'MicroPython' variant for use in SoCs (Systems on Chip) as well. Powerful controllers such as the ESP32 from Espressif Systems offer excellent performance as well as Wi-Fi and Bluetooth functionality at an affordable price. With these features, the Maker scene has been taken by storm. Compared to other controllers, the ESP32 has a significantly larger flash and SRAM memory, as well as a much higher CPU speed. Due to these characteristics, the chip is not only suitable for classic C applications, but also for programming with MicroPython. This book introduces the application of modern one-chip systems. In addition to the technical background, the focus is on MicroPython itself. After the introduction to the language, the programming skills learned are immediately put into practice. The individual projects are suitable for use in the laboratory as well as for everyday applications. So, in addition to the actual learning effect, the focus is also on the joy of building complete and useful devices. By using laboratory breadboards, circuits of all kinds can be realized with little effort, turning the testing and debugging of the 100% homebrew projects into an instructive pleasure. The various applications, such as weather stations, digital voltmeters, ultrasound range finders, RFID card readers or function generators, make the projects presented ideally suited for practical courses or subject and study work in the natural sciences, or in science and technology classes.

As demand for solar panel installation has risen sharply, especially for installations larger than balcony power plants, the order books of solar companies are full. If you ask for a quote today, you may have to wait a while, if your request isn't simply postponed indefinitely. Another consequence of the solar boom is that some companies are charging very high prices for installations. Yet there is an obvious and radical solution to the problem of excessive prices: Do it yourself, as the English say. The price of materials is currently affordable, and it's the ideal time for those who do the work themselves. They couldn't save more. Add to this the satisfaction of doing something useful, both economically and ecologically, and the pleasure of building yourself. In this special issue, you'll find a wide selection of Elektor assemblies, from solar panel controllers to solar water heaters and solar panel orientation systems. The issue also contains practical information on solar panel installation and the technology behind them. Finally, there are a number of articles on the subject of balcony power plants, from how to install them to how to connect them to the Internet...

Third, extended and revised edition with AVR Playground and Elektor Uno R4 Arduino boards have become hugely successful. They are simple to use and inexpensive. This book will not only familiarize you with the world of Arduino but it will also teach you how to program microcontrollers in general. In this book theory is put into practice on an Arduino board using the Arduino programming environment. Some hardware is developed too: a multi-purpose shield to build some of the experiments from the first 10 chapters on; the AVR Playground, a real Arduino-based microcontroller development board for comfortable application development, and the Elektor Uno R4, an Arduino Uno R3 on steroids. The author, an Elektor Expert, provides the reader with the basic theoretical knowledge necessary to program any microcontroller: inputs and outputs (analog and digital), interrupts, communication busses (RS-232, SPI, I²C, 1-wire, SMBus, etc.), timers, and much more. The programs and sketches presented in the book show how to use various common electronic components: matrix keyboards, displays (LED, alphanumeric and graphic color LCD), motors, sensors (temperature, pressure, humidity, sound, light, and infrared), rotary encoders, piezo buzzers, pushbuttons, relays, etc. This book will be your first book about microcontrollers with a happy ending! This book is for you if you are a beginner in microcontrollers, an Arduino user (hobbyist, tinkerer, artist, etc.) wishing to deepen your knowledge,an Electronics Graduate under Undergraduate student or a teacher looking for ideas. Thanks to Arduino the implementation of the presented concepts is simple and fun. Some of the proposed projects are very original: Money Game Misophone (a musical fork) Car GPS Scrambler Weather Station DCF77 Decoder Illegal Time Transmitter Infrared Remote Manipulator Annoying Sound Generator Italian Horn Alarm Overheating Detector PID Controller Data Logger SVG File Oscilloscope 6-Channel Voltmeter All projects and code examples in this book have been tried and tested on an Arduino Uno board. They should also work with the Arduino Mega and every other compatible board that exposes the Arduino shield extension connectors. Please note For this book, the author has designed a versatile printed circuit board that can be stacked on an Arduino board. The assembly can be used not only to try out many of the projects presented in this book but also allows for new exercises that in turn provide the opportunity to discover new techniques. Also available is a kit of parts including the PCB and all components. With this kit you can build most of the circuits described in the book and more.

A Fast-Lane Ride From Concept to Project The core of the book explains the use of the Raspberry Pi Zero 2 W running the Python programming language, always in simple terms and backed by many tested and working example projects. On part of the reader, familiarity with the Python programming language and some experience with one of the Raspberry Pi computers will prove helpful. Although previous electronics experience is not required, some knowledge of basic electronics is beneficial, especially when venturing out to modify the projects for your own applications. Over 30 tested and working hardware-based projects are given in the book, covering the use of Wi-Fi, communication with smartphones and with a Raspberry Pi Pico W computer. Additionally, there are Bluetooth projects including elementary communication with smartphones and with the popular Arduino Uno. Both Wi-Fi and Bluetooth are key features of the Raspberry Pi Zero 2 W. Some of the topics covered in the book are: Raspberry Pi OS installation on an SD card Python program creation and execution on the Raspberry Pi Zero 2 W Software-only examples of Python running on the Raspberry Pi Zero 2 W Hardware-based projects including LCD and Sense HAT interfacing UDP and TCP Wi-Fi based projects for smartphone communication UDP-based project for Raspberry Pi Pico W communication Flask-based webserver project Cloud storage of captured temperature, humidity, and pressure data TFT projects Node-RED projects Interfacing to Alexa MQTT projects Bluetooth-based projects for smartphone and Arduino Uno communications
