With the availability of free and open source C/C++ compilers today, you might wonder why someone would be interested in assembler language. What is so compelling about the RISC-V Instruction Set Architecture (ISA)? How does RISC-V differ from existing architectures? And most importantly, how do we gain experience with the RISC-V without a major investment? Is there affordable hardware available? The availability of the Espressif ESP32-C3 chip provides a way to get hands-on experience with RISC-V. The open sourced QEMU emulator adds a 64-bit experience in RISC-V under Linux. These are just two ways for the student and enthusiast alike to explore RISC-V in this book. The projects in this book are boiled down to the barest essentials to keep the assembly language concepts clear and simple. In this manner you will have “aha!” moments rather than puzzling about something difficult. The focus in this book is about learning how to write RISC-V assembly language code without getting bogged down. As you work your way through this tutorial, you’ll build up small demonstration programs to be run and tested. Often the result is some simple printed messages to prove a concept. Once you’ve mastered these basic concepts, you will be well equipped to apply assembly language in larger projects.

This book is about teaching the Python programming language using the Raspberry Pi 4 computer. The book makes an introduction to Raspberry Pi 4 and then teaches Python with the topics: variables, strings, arrays, matrices, tuples, lists, dictionaries, user functions, flow of control, printing, keyboard input, graphics, GUI, object oriented programming and many more topics. The book is aimed for beginners, students, practising engineers, hobbyists, and for anyone else who may want to learn to program in Python. The book includes many example programs and case studies. All the example programs and case studies have been tested fully by the author and are all working. The example programs aim to teach the various programming concepts of Python. The case studies cover the use of Python in the analysis and design of electronic circuits. Some of the case study topics are: Resistor colour code identification Resistive potential divider circuits Resistive attenuator design Zener diode voltage regulator design RC and RLC transient circuits Circuit frequency response Saving data on external memory stick Mesh and node circuit analysis using matrices Resonance in RLC circuits Transistor Biasing analysis Transistor amplifier design Design of active filters Interfacing hardware with GPIO, I²C and SPI Using Wi-Fi with Python and TCP/IP and UDP programs Using Bluetooth from Python Full program listings of all the programs used in the book are available at the Elektor website of the book. Readers should be able just to copy and use these programs in their Raspberry Pi projects without any modifications.

LoRaWAN, Sigfox, NB-IoT & LTE-M Compared The Internet of Things depends on a critical question. How do you connect devices that must operate for years on tiny batteries, often miles from the nearest power outlet? This Elektor Technical Brief provides a practical guide to the technologies that have become the backbone of long-range, low-power IoT connectivity. Compiled by the Elektor Content Team, this concise technical brief examines the real engineering tradeoffs behind today’s leading Low-Power Wide-Area Network (LPWAN) technologies: LoRaWAN, Sigfox, NB-IoT, and LTE-M. By referencing a wide range of Elektor articles and other online content, this document explains why link budget, noise, bandwidth, and power consumption ultimately determine system performance. From there, it explores the architectures, strengths, limitations, and deployment realities of each major LPWAN technology, helping you understand not just how they work, but when and why to use them. Whether you’re designing smart meters, industrial sensors, agricultural monitoring systems, asset trackers, or connected infrastructure, this guide provides the insights needed to make informed connectivity decisions. Along the way, you’ll discover: Why LPWAN technologies emerged and where they fit in the IoT landscape The RF fundamentals that drive range, reliability, and battery life Details about LoRaWAN, Sigfox, NB-IoT, and LTE-M Practical comparisons of power, coverage, latency, cost, and deployment models Guidance for selecting the right LPWAN technology for your application Emerging trends shaping the future of long-range IoT connectivity Clear, accessible, and grounded in real engineering practice, this Technical Brief helps you move beyond specifications and marketing claims to understand what matters most. If you’re building connected products that need to survive in the field — not just in the lab — this is the LPWAN guide you’ll want at your side. Elektor helped launch the first wave of electronics makers in 1961. Since then, our global community has grown by hundreds of thousands of active members (comprising professional engineers, makers, and students) and more than 500 contributing experts. Every day, we inspire members to design and earn money with electronics.
