In dit boek gebruiken we JAL (Just Another Language) om de PIC-microcontroller te programmeren in 60 oefeningen. JAL is makkelijk in gebruik en is een goede basis om programmeren in andere talen snel te leren. Na het lezen en toepassen van de voorbeelden in dit boek kan iedereen die zich hierin serieus heeft verdiept met behulp van JAL zelf de microcontroller aansturen. Je leert onder meer het programmeren van timers, analoog/digitaal omzetters, comparators, pulsbreedte regeling voor motoren en geluid, LED- en LCD-scherm aansturing, USB-connectie en communicatiemogelijkheden met computers of andere microcontrollers. Ook weet je aan het eind van het boek wat je moet doen om nu nog onbekende mogelijkheden te gaan toepassen. Met deze kennis kan iedereen van beginner tot meer gevorderde zijn creativiteit vorm geven in projecten met microcontrollers. Wil je verder met leren programmeren dan legt dit boek ook een zeer goede basis. Wie goed met JAL overweg kan en zich de gestructureerde wijze van denken heeft aangeleerd, zal de stap naar andere programmeertalen zoals Python, C++ enz. kunnen maken. Ook het programmeren van minicomputers zoals de Raspberry Pi en Arduino zijn mogelijkheden. Om te starten is geen kennis van elektronica nodig. Wie niets weet van elektronica, krijgt overal in het boek de noodzakelijke kennis aangereikt. Alle belangrijke en benodigde informatie staat in de tekst.

The Basics, New Ideas & Applications Build digital electronics from the ground up—and take it all the way to practical circuits you can use. This book guides you through the core principles of digital technology with a strongly hands-on approach. You’ll begin with the essentials: signals, devices for working with them, and what "logic 0" and "logic 1" mean in real hardware. Simple demonstration setups made from easy-to-find parts (LEDs, diodes, resistors, switches) help you see how logic behaves, making the theory click before you move on. From there, you’ll explore a wide range of logic elements and how they’re implemented, including classic logic families such as TTL and CMOS. The fundamentals section covers the building blocks of digital systems: flip-flops, Schmitt triggers, registers, counters and dividers, encoders/ decoders, multiplexers/demultiplexers, plus A/D and D/A conversion and timing circuits. Next, the book invites you into "new ideas" in digital electronics—universal logic elements, unconventional approaches (including thyristor-based and fractional logic), and creative logic functions that can inspire original designs. Finally, a large, well-organized collection of application circuits turns knowledge into projects: electronic switches and selectors, pulse generators, PWM regulators, frequency multipliers/dividers, phase shifters, and digital filters. Study it deeply, and you’ll gain not only understanding—but the ability to design and debug digital circuits independently.

The Most Iconic Oscilloscopes in Electronics History The 7000 Series was the most iconic family of oscilloscopes in the history of technology. Introduced in 1969 by Tektronix, the sector’s leader at the time, this remarkable line of instruments defined an era and became a benchmark for generations of engineers, researchers, and technicians. Throughout the 1970s and well beyond, 7000-Series oscilloscopes were a constant presence in laboratories, universities, and industrial facilities around the world. Their modular plug-in architecture, exceptional flexibility, and outstanding performance embodied the engineering philosophy that made Tektronix synonymous with accuracy, innovation, and reliability. This book offers an in-depth exploration of the 7000-Series oscilloscopes, combining historical context, technical analysis, and practical insight into their design and restoration. Conceived as a continuation of Tektronix Epic Oscilloscopes, this work expands the subject into two volumes: the first devoted to mainframes and core technologies, the second focused entirely on plug-ins.

Learning Embedded Systems with STM32 Nucleo Boards Embedded programming has become more accessible than ever before. Development boards are inexpensive, software tools are easy to install, and the Arduino IDE provides a familiar environment for creating embedded applications. Combined with the STM32 Nucleo family of development boards, it offers an excellent platform for learning how modern microcontrollers interact with the physical world. This book introduces embedded programming using the Arduino environment on STM32 Nucleo boards. You will learn how a microcontroller continuously reads inputs, processes information, and controls outputs in a predictable real-time loop. Through practical examples, you will discover how to control LEDs, read switches and sensors, generate PWM signals, drive motors, and exchange data with other devices, all while becoming familiar with the capabilities of STM32 microcontrollers. Although the STM32 family includes devices with different performance levels, memory sizes, and peripheral sets, they all share the same architectural concepts. Digital and analog I/O, timers, interrupts, PWM, communication interfaces, and low-power operation are fundamental features found throughout the STM32 ecosystem. Understanding these building blocks will enable you to work confidently with a wide range of STM32 devices, from entry-level microcontrollers to more advanced applications. By focusing on practical programming techniques rather than hardware complexity, this book develops skills that remain useful well beyond the examples presented. Whether you are taking your first steps in embedded systems or expanding your experience with STM32 microcontrollers, you will gain a solid understanding of both the Arduino development environment and the principles that underpin embedded software design.

This book contains 50 fun and exciting projects for PIC microcontrollers such as a laser alarm, USB teasing mouse, eggtimer, youth repellent, soundswitch, capacitive liquid level gauge, 'finger in the water' sensor, guarding a room using a camera, mains light dimmer (110-240 volts), talking microcontroller and much more. Several different techniques are discussed such as relay, alternating current control including mains, I²C, SPI, RS232, USB, pulse width modulation, rotary encoder, interrupts, infrared, analog-digital conversion (and the other way around), 7-segment display and even CAN bus. You can use this book to build the projects for your own use. The clear explanations, schematics and even pictures of each project make this a fun activity. For each project the theory is discussed and why the project has been executed in that particular way. That means you can also use this book as a studybook, or as basis for larger and more complicated projects. All projects use a breadboard so modification and expansion is easy. Three PIC microcontrollers are used, the 16f877A, 18f4455 and 18f4685. It is also discussed how you can migrate your project from one microcontroller to another – 15 types are supported - including two example projects. All software that is used in this book can be downloaded for free. That also applies to the open source programming language JAL. This powerful and yet easy to learn language is used by hobbyists as well as professionals. This book can also be used as a reference guide. It explains all JAL commands, as well as the expansion libraries. Using the index you can easily find example projects that illustrate the use of these commands. Even when you have built all projects in this book you will still want to keep it within arm's reach.
