Elektor Bundles Mikrocontroller-Praxiskurs für Arduino-Einsteiger (Bundle)
Mit dem Elektor Arduino Nano Trainingsboard (MCCAB) eigene Projekte realisieren Der Mikrocontroller ist das wohl faszinierendste Teilgebiet der Elektronik, denn aufgrund der Vielzahl von Funktionen, die er auf seinem Chip vereinigt, ist er für den Entwickler ein universelles Multi-Tool zur Realisierung seiner Projekte. Praktisch jedes Gerät des täglichen Gebrauchs wird heute von einem Mikrocontroller gesteuert. Für einen elektronischen Laien blieb es aufgrund der Komplexität bisher allerdings ein Wunschtraum, eigene Ideen mit einem Mikrocontroller zu realisieren. Das Arduino-Konzept hat den Einsatz von Mikrocontrollern weitgehend vereinfacht, sodass jetzt auch Laien eigene Elektronik-Ideen mit einem Mikrocontroller verwirklichen können. Buch & Hardware im Bundle: 'Learning by Doing' Dieses im Bundle mitgelieferte Buch (im großen A4-Format) zeigt, wie man auch ohne große Erfahrung in Elektronik und Programmiersprachen eigene Projekte mit einem Mikrocontroller realisieren kann. Es ist ein Mikrocontroller-Praxiskurs für Einsteiger, denn nach einem Überblick über die Interna des Mikrocontrollers und einer Einführung in die Programmiersprache C liegt der Schwerpunkt des Kurses auf den praktischen Übungen. Der Leser eignet sich die erforderlichen Kenntnisse durch 'Learning by Doing' an: in dem umfangreichen Praxisteil mit 12 Projekten und 46 Übungen wird das im vorderen Teil des Buches Gelernte mit vielen Beispielen unterlegt. Die Übungen sind dabei so aufgebaut, dass der Bearbeiter eine Aufgabenstellung erhält, die er mit seinem im Theorieteil des Buches aufgebauten Wissen löst. Für jede Übung gibt es anschließend eine ausführlich erklärte und kommentierte Musterlösung, die dem Bearbeiter bei Problemen weiterhilft und die er mit seiner eigenen Lösung vergleichen kann. Arduino IDE In der Arduino IDE, einer Software-Entwicklungsumgebung, die kostenlos auf den eigenen PC heruntergeladen werden kann und die das gesamte Softwarepaket enthält, das für ein eigenes Mikrocontroller-Projekt benötigt wird, schreibt der Bearbeiter mit dem Editor der IDE seine Programme („Apps“) in der Programmiersprache C. Der in die Arduino IDE integrierte Compiler übersetzt sie in die Bits und Bytes, die der Mikrocontroller versteht und die dann über ein USB-Kabel in den Speicher des Mikrocontrollers auf dem Elektor Arduino Nano Trainingsboard (MCCAB) geladen werden. Externe Sensoren, Motoren oder Baugruppen abfragen oder steuern Das Elektor Arduino Nano Trainingsboard (MCCAB) enthält neben einem Mikrocontrollermodul Arduino Nano alle für die Übungen benötigten Bauteile wie Leuchtdioden, Schalter, Taster, akustische Signalgeber usw. Auch externe Sensoren, Motoren oder Baugruppen können mit diesem Mikrocontroller-Übungssystem abgefragt oder gesteuert werden.

QuantAsylum QuantAsylum QA403 24-bit Audio Analyzer
The QA403 is QuantAsylum's fourth-generation audio analyzer. The QA403 extends the functionality of the QA402 with improved noise and distortion performance, in addition to a flatter response at band edges. The compact size of the QA403 means you can take it just about anywhere. Features 24-bit ADC/DAC Up to 192 kS/s Fully isolated from PC Differential Input/Output USB powered Built-in Attenuator Fast Bootup and Driverless The QA403 is a driverless USB device, meaning it’s ready as soon as you plug it in. The software is free and it is quick and easy to move the hardware from one machine to the next. So, if you need to head to the factory to troubleshoot a problem or take the QA403 home for a work-from-home day, you can do it without hassle. No-Cal Design The QA403 comes with a factory calibration in its flash memory, ensuring consistent unit-to-unit performance. On your manufacturing line you can install another QA403 and be confident what you read on one unit will be very similar to the next unit. It is not expected that re-calibration will be required at regular intervals. Measurements Making basic measurements is quick and easy. In a few clicks you will understand the frequency response, THD(+N), gain, SNR and more of your device-under test. Dynamic Range The QA403 offers 8 gain ranges on the input (0 to +42 dBV in 6 steps), and 4 gain ranges on the output (-12 to +18 dBV in 10 dB steps). This ensures consistent performance over very wide ranges of input and output levels. The maximum AC input to the QA403 is +32 dBV = 40 Vrms. The maximum DC is ±40 V, and the maximum ACPEAK + DC = ±56 V. Easy Programmability The QA403 supports a REST interface, making it easy to automate measurements in just about any language you might anticipate. From Python to C++ to Visual Basic—if you know how to load a web page in your favorite language, you can control the QA403 remotely. Measurements are fast and responsive, usually with dozens of commands being processed per second. Isolated and USB Powered The QA403 is isolated from the PC, meaning you are measuring your DUT and not chasing some phantom ground loop. The QA403 is USB powered, like nearly all our instruments. If you are setting up remotely, throw a powered hub in your bag and your entire test setup can be running with a minimum of cables. Goodbye Soundcard, Hello QA403 Tired of trying to make a soundcard work? The calibration nightmare? The lack of gain stages? The limited drive? Are you tired of dealing with the fixed input ranges? The worry that you might destroy it with too much DC or AC? Tired of the ground loops? That’s why QuantAsylum built the QA403.
