Arduinonext is an initiative powered by an electronics and microcontrollers specialist team aiming to help all those who are entering in the technology world, using the well-known Arduino platform to take the next step in electronics.
We strive to bring you the necessary knowledge and experience for developing your own electronics applications; interacting with environment; measuring physical parameters; processing them and performing the necessary control actions.
This is the first title in the 'Hands-On' series in which Arduino platform co-founder, David Cuartielles, introduces board programming, and demonstrates the making of an 8-bit Sound Generator.
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.

Note: NodeMCU is the name of both a firmware and a boardNodeMCU is an open source IoT platform, whose firmware runs on Espressif's SoC Wi-Fi ESP8266, based on the ESP8266 nonOS SDK. Its hardware is based on the ESP-12 module. The scripting language is Lua which allows to use many open source projects like lua-cjson and spiffs. Features Wi-Fi Module – ESP-12E module similar to ESP-12 module but with 6 extra GPIOs. USB – micro USB port for power, programming and debugging Headers – 2x 2.54 mm 15-pin header with access to GPIOs, SPI, UART, ADC, and power pins Reset & Flash buttons Power: 5V via micro USB port Dimensions: 49 x 24.5 x 13 mm
AVR Architecture and Programming An in-depth look at the 8-bit AVR architecture found in ATtiny and ATmega microcontrollers, mainly from a software and programming point of view. Explore the AVR architecture using C and assembly language in Microchip Studio (formerly Atmel Studio) with ATtiny microcontrollers. Learn the details of how AVR microcontrollers work internally, including the internal registers and memory map of ATtiny devices. Program ATtiny microcontrollers using an Atmel-ICE programmer/debugger, or use a cheap hobby programmer, or even an Arduino Uno as a programmer. Most code examples can be run using the Microchip Studio AVR simulator. Learn to write programs for ATtiny microcontrollers in assembly language. See how assembly language is converted to machine code instructions by the assembler program. Find out how programs written in the C programming language end up as assembly language and finally as machine code instructions. Use the Microchip Studio debugger in combination with a hardware USB programmer/debugger to test assembly and C language programs, or use the Microchip Studio AVR simulator. DIP packaged ATtiny microcontrollers are used in this volume for easy use on electronic breadboards, targeting mainly the ATtiny13(A) and ATtiny25/45/85. Learn about instruction timing and clocks in AVR microcontrollers using ATtiny devices. Be on your way to becoming an AVR expert with advanced debugging and programming skills.

The iCEBreaker FPGA board is an open-source educational FPGA development board.
The iCEBreaker is great for classes and workshops teaching the use of the open source FPGA design flow through Yosys, nextpnr, IceStorm, Icarus Verilog, Amaranth HDL and others. This means the board is low cost and has a nice set of features to allow for the design of interesting classes and workshop exercises. At the same time it allows the user to use the proprietary vendor tools if they choose to.
After the workshop the boards can be easily used as a development board as most GPIO are exposed, broken out and configurable through jumpers on the back of the board. There is only a minimal amount of buttons and LED that can't be disconnected and used for your own purposes.

In this book the author presents all essential aspects of microcontroller programming, without overloading the reader with unnecessary or quasi-relevant bits of information. Having read the book, you should be able to understand as well as program, 8-bit microcontrollers.
The introduction to microcontroller programming is worked out using microcontrollers from the PIC series. Not exactly state-of-the-art with just 8 bits, the PIC micro has the advantage of being easy to comprehend. It is offered in a DIP enclosure, widely available and not overly complex. The entire datasheet of the PIC micro is shorter by decades than the description of the architecture outlining the processor section of an advanced microcontroller. Simplicity has its advantages here. Having mastered the fundamental operation of a microcontroller, you can easily enter into the realms of advanced softcores later.
Having placed assembly code as the executive programming language in the foreground in the first part of the book, the author reaches a deeper level with ‘C’ in the second part. Cheerfully alongside the official subject matter, the book presents tips & tricks, interesting measurement technology, practical aspects of microcontroller programming, as well as hands-on options for easier working, debugging and faultfinding.
