An Ultra-Rapid Programming Course
This book serves as the very first step to for novices to learn Python programming. The book is divided into ten chapters. In the first chapter, readers are introduced to the basics of Python. It has the detailed instructions for installation on various platforms such as macOS, Windows, FreeBSD, and Linux. It also covers the other aspects of Python programming such as IDEs and Package Manager. The second chapter is where the readers get an opportunity to have a detailed hands-on with Python programming. It covers a group of built-in data structures popularly known as Python Collections. The third chapter covers the important concepts of strings, functions, and recursion.
The fourth chapter focuses on the Object-Oriented Programming with Python. The fifth chapter discusses most commonly used custom data structures such as stack and queue. The sixth chapter spurs the creativity of the readers with Python’s Turtle graphics library. The seventh chapter explores animations and game development using the Pygame library. The eighth chapter covers handling data stored in a variety of file formats. The ninth chapter covers the area of Image processing with Wand library in Python. The tenth and the final chapter presents an array of assorted handy topics in Python.
The entire book follows a step-by-step approach. The explanation of the topic is always followed by a detailed code example. The code examples are also explained in suitable detail and they are followed by the output in the form of text or screenshot wherever possible. Readers will become comfortable with Python programming language by closely following the concepts and the code examples in this book. The book also has references to external resources for readers to explore further.
A download of the software code, and links to tutorial videos can be found on the Elektor website.
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.

If you are going to be drilling, we recommend drilling on FR1 substrates. Unlike FR4, FR1 dust does not contain fiber glass. It is also a softer material, which means a less wear and tear on the drill bits. Download the template and incorporate them into your design here. 10 substrates included.

Wiki
The Raspberry Pi A+ Case has been designed to fit both the Pi 3 Model A+ and the Pi 1 Model A+. The high-quality ABS construction consists of two parts. The base features cut-outs to allow access to the microSD Card and the the HDMI, audio/video and USB ports, as well as the power connector.
Deze SPD3000X Series Linear Programmable DC Power Supply heeft een 4,3-inch TFT LCD-scherm, is te programmeren en heeft Real Time Wave Display, wat gebruikers een geheel nieuwe ervaring geeft. Hij heeft drie aparte uitgangen: twee regelbare uitgangen, en een instelbare uitgang van 2,5V, 3,3V en 5V. Hij heeft ook beveiligingsfuncties tegen kortsluiting en overbelasting, en kan goed worden ingezet bij productie en ontwikkeling.

Elektronica moeilijk? De titel van dit boek geeft het antwoord!
In deze 3-in-1-band wordt de elektronica vanuit de praktijk benaderd. Dat wil zeggen veel praktijk in de vorm van experimenten en een minimum aan theorie. Zo raakt u stap voor stap vertrouwd met de behandelde onderwerpen. Daarbij ontstaan gaandeweg ook een flink aantal praktisch bruikbare schakelingen. Het gaat bij de elektronicahobby tenslotte om het bouwen of uitdenken van allerlei praktische of leuke schakelingen.
Aan het eind van elk deel is een aanhangsel opgenomen met aanvullende informatie en de gegevens van een groot aantal elektronische componenten, zodat na dit boek ook eigen ideeën en experimenten kunnen worden aangepakt.
In deze 3-in-1-band zijn de eerste drie delen uit de serie “Elektronica echt niet moeilijk” samengevoegd:
Deel 1: experimenten met gelijkstroom
Deel 2: experimenten met wisselstroom
Deel 3: experimenten met digitale techniek
High-quality ABS construction Removable side panels and lid for easy access to GPIO, camera and display connectors Light pipes for power and activity LEDs Extraordinarily handsome Colour: white/red
