in 10 captivating lessons Using the lessons in this book you learn how to program a microcontroller. You’ll be using JAL, a free but extremely powerful programming language for PIC microcontrollers, which enjoys great popularity in the hobby world. Starting out from scratch virtually, you slowly build up the knowledge. No previous knowledge is needed: anyone can get started with this book. Assuming you have absorbed all lessons – meaning you have actually completed all the exercises – you should be confident to write PIC microcontroller programs, as well as read and understand programs written by other people. JAL commands You learn the function of JAL commands such as include, pin, delay, forever loop, while loop, case, exit loop, repeat until, if then, as well as the use of functions, procedures and timer- and port interrupts. JAL programs You make an LED blink, build a time switch, measure a potentiometer’s wiper position, produce sounds, suppress contact bounce, and control the brightness of an LED. And of course you learn to debug, meaning: how to spot and fix errors in your programs. Hardware You learn to recognize various components including the PIC microcontroller, potentiometer and quartz crystal, and how to wire up a PIC microcontroller and effectively link it to your PC. A breadboard is used for the purpose, allowing you to easily modify the component arrangement for further experimenting. The companion software with this book can be downloaded free of charge, including the JAL programming language. In addition, you may order a kit of parts so you don’t have to go shopping for the required components. Especially for a beginner, this is the easiest way to start with this unique pastime. Having finished this book does not mean you are through with your pastime. You can get your hands dirty again, and if desired use other books packed with fun projects using the JAL programming language. More information may be found at the end of the lessons in the chapter "Done! What’s next?""

ÉLECTRICITÉ PHOTOVOLTAÏQUE = ÉLECTRICITÉ GRATUITE Nous sommes désormais plus qu'heureux de poursuivre nos recherches sur notre propre autonomie et de veiller à ce que notre production électrique photovoltaïque soit appropriée ! D'abord on en rêve, puis vient l'étape du calcul : comparer le coût du kilowattheure d'origine du nucléaire (environnement à partir de centimes d'euro) et le calcul du kilowattheure d'origine photovoltaïque (l'environnement de 22 centimes de l'euro*), et nous saurons où en sont nos motivations d'écocitoyens. Gérard Guihéneuf, l'auteur de ce nouveau livre, pense qu'il ne faut pas se contenter d'aligner chiffres et idées. La nouvelle approche du processus de création d'entreprise se base sur la compréhension et les dimensions des installations des bâtiments domestiques dans le domaine public en 2009 et sur l'actualité des techniques et pratiques de réponse aux questions qui se posent lors de l'électrification des le site isolé ! La conception de projets simples, comme un contexte domestique, et d'un commentaire électrique standard, comme un système d'énergie photovoltaïque, trois emplacements réguliers : un abri dans le jardin, un garage et un mobil-home. L'économie est spectaculaire lorsqu'il s'agit de composants électroniques et d'assemblages de certains constituants essentiels, car les régulateurs de charge, les onduleurs et les panneaux solaires ne suffisent pas à l'entretien autonome du site. Si vous souhaitez en savoir plus sur l'électrification professionnelle de votre chantier, vous pouvez en savoir plus sur les dimensions des éléments constitutifs sans sacrifier l'efficacité ! Vous pouvez également utiliser la copie du Gerber et du Sprint Layout pour les circuits imprimés de la livrée. *avec les batteries en cours de reconditionnement lors de la panne photovoltaïque en cours et dans les vingt-cinq

De SQ-serie handsfree PCBite-sondes van Sensepeek zijn geïsoleerd, worden geleverd met meegeleverde kleurgecodeerde kabelhouders en hebben een lager zwaartepunt waardoor ze nog stabieler zijn vergeleken met de originele SP-serie sondes. Alle geliefde kenmerken van handsfree meten, een verwisselbare testnaald met veertip en het minimalistische ontwerp zijn behouden gebleven, waardoor traditionele en draagbare sondes overbodig zijn geworden. Kenmerken Alle handsfree sondes van Sensepeek maken directe metingen of lange triggersessies een fluitje van een cent. Geen soldeerdraden meer om uw sonde aan te sluiten of ingewikkelde gereedschappen om in te stellen, u hoeft alleen maar de sondenaald op een willekeurig testpunt of onderdeel in het signaalpad te plaatsen en los te laten. Bespaart tijd en frustratie tijdens ontwikkeling, verificatie en reparaties. Het minimalistische ontwerp en de veerbelaste testnaald maken het mogelijk om tegelijkertijd te meten op fijne toonhoogtecomponenten en signalen in de buurt. Zowel de lengte als het gewicht van de SQ-sondes zijn perfect uitgebalanceerd voor gebruik met PCBite PCB-houders en basisplaat, wat een must is voor handsfree functioneren. De sondehouder wordt geleverd met een krachtige magneet in de basis, zoals bij alle PCBite-sondes en -houders, waardoor de sonde gemakkelijk te plaatsen en te verplaatsen is. De sondes uit de SQ-serie kunnen zonder de sondehouder in de hand worden gebruikt, omdat ze een geïsoleerde handgreep hebben, maar hun volledige potentieel wordt benut bij handsfree meten. Inbegrepen 4x PCBite PCB-houders 2x SQ10-sondes en testnaalden met pintip (rood/zwart) 2x Banaan naar dupont-testdraden (rood/zwart) 1x Grote bodemplaat (A4) 1x Isolatiehoes voor de bodemplaat (A4) 1x Set gele isolatieringen voor de PCB-houders 1x Set kabelhouders (rood/zwart) 2x Extra testnaalden 1x Microvezeldoek Downloads User Guide (PCBite Kit) User Guide (SQ10)

Praktische Einführung in 3D-Modellierung vom Gehäuse bis zu Frontplatten Ein historisches Bauteil einbetten, eine professionell anmutende Heimstätte für eine Leiterplatte schaffen oder ein komplexes Gerät mit Chassis konstruieren – diese und viele andere Herausforderungen werden mit FreeCAD zu einem anregenden Vergnügen. Hat man die grundlegenden Prozesse erst einmal verinnerlicht, sind der Fantasie praktisch keine Grenzen mehr gesetzt. Der Einstieg in ein neues Programm ist immer schwierig – besonders wenn es sich um ein so vielfältiges Werkzeug wie FreeCAD handelt. Überschaubare, aber zugleich gut verwendbare Einzelteile liefern in diesem Buch den Anfangspunkt. Das Zusammensetzen dieser Komponenten führt später zu Baugruppen. In der Vielfalt der Möglichkeiten von FreeCAD wird ein gangbarer Weg gezeigt. Das beschriebene Vorgehen ist exemplarisch – die Beispiele lassen sich daher leicht auf eigene Aufgaben anwenden. Die Geräte wurden vom Autor angefertigt und mit Fotos illustriert. Eine 3D-Konstruktion erfordert etwas Aufwand, der sich aber lohnt: Neben einer beeindruckenden Darstellung von Projekten wird zugleich die Möglichkeit geliefert, z. B. Blechteile zur Fertigung abzuwickeln und für die Werkstatt aussagekräftige Zeichnungen zu exportieren. Schon bald werden Sie auf FreeCAD nicht mehr verzichten wollen!

Third, extended and revised edition with AVR Playground and Elektor Uno R4 Arduino boards have become hugely successful. They are simple to use and inexpensive. This book will not only familiarize you with the world of Arduino but it will also teach you how to program microcontrollers in general. In this book theory is put into practice on an Arduino board using the Arduino programming environment. Some hardware is developed too: a multi-purpose shield to build some of the experiments from the first 10 chapters on; the AVR Playground, a real Arduino-based microcontroller development board for comfortable application development, and the Elektor Uno R4, an Arduino Uno R3 on steroids. The author, an Elektor Expert, provides the reader with the basic theoretical knowledge necessary to program any microcontroller: inputs and outputs (analog and digital), interrupts, communication busses (RS-232, SPI, I²C, 1-wire, SMBus, etc.), timers, and much more. The programs and sketches presented in the book show how to use various common electronic components: matrix keyboards, displays (LED, alphanumeric and graphic color LCD), motors, sensors (temperature, pressure, humidity, sound, light, and infrared), rotary encoders, piezo buzzers, pushbuttons, relays, etc. This book will be your first book about microcontrollers with a happy ending! This book is for you if you are a beginner in microcontrollers, an Arduino user (hobbyist, tinkerer, artist, etc.) wishing to deepen your knowledge,an Electronics Graduate under Undergraduate student or a teacher looking for ideas. Thanks to Arduino the implementation of the presented concepts is simple and fun. Some of the proposed projects are very original: Money Game Misophone (a musical fork) Car GPS Scrambler Weather Station DCF77 Decoder Illegal Time Transmitter Infrared Remote Manipulator Annoying Sound Generator Italian Horn Alarm Overheating Detector PID Controller Data Logger SVG File Oscilloscope 6-Channel Voltmeter All projects and code examples in this book have been tried and tested on an Arduino Uno board. They should also work with the Arduino Mega and every other compatible board that exposes the Arduino shield extension connectors.
