Learning circuit design the fun way Welcome to the world of electronics! Getting started in electronics is not as difficult as you may think. Using this book, you will explore and learn the most important electrical and electronics engineering concepts in a fun way by doing various experiments and by simulating circuits. It will teach you electronics practically without getting into complex technical jargon and long calculations. As a result, you will be creating your own projects soon. No prior knowledge of electronics is required, only some basic algebra is used in a few simple calculations. Many tested and working projects and simulations are presented to familiarise yourself with the construction of electronic circuits. Circuit simulation is introduced at an early stage to enable you to experiment with circuits easily without breaking anything. You will learn: The concepts of voltage, current, and power AC and DC Basic lamp circuits with switches Passive components: resistors, capacitors & inductors RC & RCL circuits Electromagnetism Loudspeakers, relays, buzzers, and transformers Active components: diodes & LEDs, bipolar transistors & MOSFETs Transistor-based switching circuits Optocoupler circuits Astable & monostable multivibrators Using the 555 timer IC The operational amplifier Digital logic Advanced examples: amplifiers, oscillators, filters, and sensors Test and measurement tools Microcontrollers: Arduino UNO, ESP32, Raspberry Pi Pico, and Raspberry Pi Reading datasheets and best practices for selecting components EMC & EMI and norms & regulations

An Introduction to Circuit Simulation LTspice, developed by Analog Devices, is a powerful, fast, and free SPICE simulator, schematic capture, and waveform viewer with a large database of components supported by SPICE models from all over the world. Drawing a schematic in LTspice is easy and fast. Thanks to its powerful graphing features, you can visualize the voltages and currents in a circuit, and also the power consumption of its components and much more. This book is about learning to design and simulate electronic circuits using LTspice. Among others, the following topics are treated: DC and AC circuits Signal diodes and Zener diodes Transistor circuits including oscillators Thyristor/SCR, diac, and triac circuits Operational amplifier circuits including oscillators The 555 timer IC Filters Voltage regulators Optocouplers Waveform generation Digital logic simulation including the 74HC family SPICE modeling LTspice is a powerful electronic circuit simulation tool with many features and possibilities. Covering them all in detail is not possible in a book of this size. Therefore, this book presents the most common topics like DC and AC circuit analysis, parameter sweeping, transfer functions, oscillators, graphing, etc. Although this book is an introduction to LTspice, it covers most topics of interest to people engaged in electronic circuit simulation. The book is aimed at electronic/electrical engineers, students, teachers, and hobbyists. Many tested simulation examples are given in the book. Readers do not need to have any computer programming skills, but it will help if they are familiar with basic electronic circuit design and operation principles. Readers who want to dive deeper can find many detailed tutorials, articles, videos, design files, and SPICE circuit models on the Internet. All the simulation examples used in the book are available as files at the webpage of this book. Readers can use these example circuits for learning or modify them for their own applications.

Zeitsteuerung, Scheduler, PIO und Zustandsmaschinen Multitasking ist der Schlüssel zu leistungsfähigen Embedded-Systemen, und zugleich eine der größten Herausforderungen in der Mikrocontroller-Programmierung. Dieses Buch zeigt Ihnen Schritt für Schritt, wie Sie von einem einfachen Ein-Task-Programm zu einem strukturierten, reaktionsfähigen und skalierbaren System gelangen. Dabei steht nicht nur das Wie, sondern vor allem das Warum im Mittelpunkt. Sie lernen: warum scheinbare Parallelität entsteht weshalb blockierende Programme instabil werden wie Aufgaben effizient und kontrolliert parallel ablaufen Ausgehend vom klassischen Superloop vermittelt das Buch moderne Multitasking-Strategien – von nicht-blockierender Programmierung und Tick-Systemen bis zu Task-Schedulern, Zustandsmaschinen und ereignisgesteuerten Konzepten. Der Fokus liegt auf der Praxis: Sensoren, Displays, Kommunikation und reale Anwendungen werden Schritt für Schritt integriert und mit verständlich kommentierten Beispielprogrammen erklärt. Fortgeschrittene Themen umfassen: Multicore-Programmierung mit dem Raspberry Pi Pico asynchrones Programmieren mit uasyncio RTOS-Grundlagen mit FreeRTOS die Kombination aus Multicore und RTOS Dabei werden auch die Grenzen dieser Techniken, insbesondere unter MicroPython, klar aufgezeigt. Das Buch richtet sich an ambitionierte Einsteiger und fortgeschrittene Entwickler, die Embedded-Systeme fundiert verstehen und robuste, wartbare Multitasking-Anwendungen entwickeln möchten.

Practical Multitasking Fundamentals Programming embedded systems is difficult because of resource constraints and limited debugging facilities. Why develop your own Real-Time Operating System (RTOS) as well as your application when the proven FreeRTOS software is freely available? Why not start with a validated foundation? Every software developer knows that you must divide a difficult problem into smaller ones to conquer it. Using separate preemptive tasks and FreeRTOS communication mechanisms, a clean separation of functions is achieved within the entire application. This results in safe and maintainable designs. Practicing engineers and students alike can use this book and the ESP32 Arduino environment to wade into FreeRTOS concepts at a comfortable pace. The well-organized text enables you to master each concept before starting the next chapter. Practical breadboard experiments and schematics are included to bring the lessons home. Experience is the best teacher. Each chapter includes exercises to test your knowledge. The coverage of the FreeRTOS Application Programming Interface (API) is complete for the ESP32 Arduino environment. You can apply what you learn to other FreeRTOS environments, including Espressif’s ESP-IDF. The source code is available from GitHub. All of these resources put you in the driver’s seat when it is time to develop your next uber-cool ESP32 project. What you will learn: How preemptive scheduling works within FreeRTOS The Arduino startup “loopTask” Message queues FreeRTOS timers and the IDLE task The semaphore, mutex, and their differences The mailbox and its application Real-time task priorities and its effect Interrupt interaction and use with FreeRTOS Queue sets Notifying tasks with events Event groups Critical sections Task local storage The gatekeeper task
