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.

Cytron Maker Pi RP2040 features the first microcontroller designed by Raspberry Pi – RP2040, embedded on a robot controller board. This board comes with dual channel DC motor driver, 4 servo motor ports and 7 Grove I/O connectors, ready for your next DIY robot / motion control project. Now you can build robot, while trying out the new RP2040 chip. The DC motor driver onboard is able to control 2x brushed DC motors or 1x bipolar/unipolar stepper motor rated from 3.6 V to 6 V, providing up to 1 A current per channel continuously. The built-in Quick Test buttons and motor output LEDs allow functional test of the motor driver in a quick and convenient way, without the need of writing any code. Vmotor for both DC and servo motors depends on the input voltage supplied to the board. Maker Pi RP2040 features all the goodness of Cytron's Maker series products. It too has lots of LEDs useful for troubleshooting (& visual effects), is able to make quite some noise with the onboard piezo buzzer and comes with push buttons ready to detect your touch. There are three ways to supply power to the Maker Pi RP2040 – via USB (5 V) socket, with a single cell LiPo/Li-Ion battery or through the VIN (3.6-6 V) terminals. However only one power source is needed to power up both controller board and motors at a time. Power supply from all these power sources can all be controlled with the power on/off switch onboard. Cytron Maker Pi RP2040 is basically the Raspberry Pi Pico + Maker series' goodness + Robot controller & other useful features. Therefore this board is compatible with the existing Pico ecosystem. Software, firmware, libraries and resources that are developed for Pico should work seamlessly with Cytron Maker Pi RP2040 too. CircuitPython is preloaded on the Maker Pi RP2040 and it runs a simple demo program right out-of-the-box. Connect it to your computer via USB micro cable and turn it on, you will be greeted by a melody tune and LEDs running light. Press GP20 and GP21 push buttons to toggle the LEDs on/off, while controlling any DC and servo motors connected to it to move and stop. With this demo code, you get to test the board the moment you receive it! While connected to your computer, a new CIRCUITPY drive appears. Explore and edit the demo code (code.py & lib folder) with any code editor you like, save any changes to the drive and you shall see it in action in no time. That's why we embrace CircuitPython – it's very easy to get started. Wish to use other programming lauguages? Sure, you are free to use MicroPython and C/C++ for Pico/RP2040.

All you need to know about good acoustics and sound systems in performance and worship spaces! Everyone knows that the ability to hear music in balance and to understand speech is essential in any space used for performance or worship. Unfortunately, in the early 21st century, we find that buildings with good acoustics are the exception rather than the rule. Much of the fault leading to this result can be traced to the widespread perception that acoustics is a black art. In fact, scientific acoustics as developed in the last century is a well-defined engineering practice that can lead to predictable excellent results. A basic, non-engineering understanding of acoustics will help building owners, theater managers, ministers and teachers of music, performers, and other professionals to achieve their goals of excellent acoustics in venues with which they work. Performers having a basic understanding of acoustics will be able to make the most of the acoustics of the venue in which they perform. This book helps those responsible for providing good acoustics in performance and worship spaces to understand the variables and choices entailed in proper acoustic design for performance and worship. Practicing acoustical consultants will find the book a useful reference as well. The level of presentation is comfortable and straightforward without being simplistic. If correct acoustical principles are incorporated into the design, renovation, and maintenance of performance and worship venues, good acoustics will be the result.

Unlike other Raspberry Pi boards, the Raspberry Pi Pico does not have a built-in video output. However, thanks to programmable IO (PIO) and this Pico DVI Sock, it is possible to add a DVI video output to the Raspberry Pi Pico! The Pico DVI Sock was developed by Luke Wren, a Raspberry Pi engineer, in his spare time. He has published the design online under a CC0 license, so everybody can build the hardware from his provided files. The physical video interface of the Pico DVI Sock is an HDMI connector, but it outputs a DVI signal. Historically, HDMI is a successor to DVI – so DVI signals can be simply transmitted using HDMI. Simple passive adapters allow you to connect HDMI cables to a DVI port. The DVI Sock can be soldered to one end of the Raspberry Pi Pico. Thanks to the castellated edges of the Pico, soldering is very easy. Let your creativity run wild with an additional digital video output on the Pico. Here are some suggestions / possible project ideas: Mini game console based on the Raspberry Pi Pico Output of measurement values on a monitor
