Build your textbook weather station or conduct environmental research together with the whole world. With many practical projects for Arduino, Raspberry Pi, NodeMCU, ESP32, and other development boards. Weather stations have enjoyed great popularity for decades. Every current and even every long discontinued electronics magazine has regularly featured articles on building your own weather station. Over the years, they have become increasingly sophisticated and can now be fully integrated into an automated home — although this often requires loyalty to an (expensive) brand manufacturer across all components. With your own weather and environmental data, you can keep up and measure things that no commercial station can. It’s also fun: expand your knowledge of electronics, current microcontroller development boards and programming languages in a fun and meaningful way. For less than 10 euros you can get started and record your first environmental data — with time and growing interest, you will continue to expand your system.

Wie enigszins bekend is met moderne microprocessor systemen als Arduino, kent ongetwijfeld ook de problemen met dit soort kaarten. Ze zijn te duur om voor elk project een aparte kaart aan te schaffen en zijn bovendien nogal fors van formaat. Het aardige van de ATtiny is dat de schijn bedriegt. Het lijkt een klein IC met een beperkt toepassingsgebied, maar het heeft een verbazingwekkend scala aan (speelse) mogelijkheden. Dit boek beschrijft de enorme veelzijdigheid van de ATtiny microcontroller aan de hand van ongeveer vijftig leuke elektronica projecten, speciaal gericht op de beginner.  De meeste ontwerpen zijn volledig uitgewerkt, enkele zijn meer als ontwerpidee gepresenteerd. De inhoudsopgave laat zien dat we ons op vele terreinen zullen begeven, van zonnevolger tot helling indicator. Dit boek is beslist geen theorieboek. Het is een boek dat gelezen zal worden met de soldeerbout in de hand. Voor het programmeren van de ATtiny maken we dankbaar gebruik van een Arduino kaart. Als de Arduino ingesteld word als programmer, kunnen we er de meeste Arduino “sketches” mee overzetten naar de ATtiny. We wensen u veel plezier met het nabouwen van de schakelingen.

If you can describe it, you can build it AI coding assistants are changing what makers and solopreneurs can build. Tasks that once demanded weeks of learning a new language, framework, or software stack can now be delegated to an AI—provided you know how to describe the job, judge the result, and keep control of the process. The Maker’s Guide to AI Coding is a practical guide to doing exactly that. It explains how to work with AI coding tools as collaborators rather than vending machines, how much to delegate, how to write specifications that produce useful results, and how to recognise hallucinations, context drift, overconfidence, and code that runs but is still wrong. The book is built around four increasingly ambitious projects. You begin with a browser-based RC filter analyser, then develop a live serial data plotter for Arduino and other microcontrollers. Next comes a datasheet questionand- answer tool using retrieval-augmented generation (RAG), followed by a complete multi-user resource booking system with authentication, a database, external services, background jobs, and deployment. No advanced programming background is required. The emphasis is on thinking clearly, guiding the AI, testing what it produces, and preserving the skills needed to evaluate its work. Along the way, you learn development workflow designed to remain useful as tools evolve. If you can describe what you want to build, this book shows you how to turn that description into working software.

Practical Applications and Project with Arduino, ESP32, and RP2040 Immerse yourself in the fascinating world of control engineering with Arduino and ESP32! This book offers you a practical introduction to classic and modern control methods, including PID controllers, fuzzy logic, and sliding-mode controllers. In the first part, you will learn the basics of the popular Arduino controllers, such as the Arduino Uno and the ESP32, as well as the integration of sensors for temperature and pH measurement (NTC, PT100, PT1000, and pH sensor). You will learn how to use these sensors in various projects and how to visualize data on a Nextion TFT display. The course continues with an introduction to actuators such as MOSFET switches, H-bridges, and solid-state relays, which are used to control motors and actuators. You will learn to analyze and model controlled systems, including PT1 and PT2 control. The book focuses on the implementation of fuzzy and PID controllers for controlling temperature and DC motors. Both the Arduino Uno and the ESP32 are used. The sliding-mode controller is also introduced. In the second-to-last chapter, you will explore the basics of neural networks and learn how machine learning can be used on an Arduino. In the last chapter, there is a practical example of a fuzzy controller for feeding electricity into the household grid. This book is the perfect choice for engineers, students, and electronics engineers who want to expand their projects with innovative control techniques.

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.
