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.

Easy and Affordable Digital Signal ProcessingThe aim of this book is to teach the basic principles of Digital Signal Processing (DSP) and to introduce it from a practical point of view using the bare minimum of mathematics. Only the basic level of discrete-time systems theory is given, sufficient to implement DSP applications in real time. The practical implementations are described in real time using the highly popular ESP32 DevKitC microcontroller development board. With the low cost and extremely popular ESP32 microcontroller, you should be able to design elementary DSP projects with sampling frequencies within the audio range. All programming is done using the popular Arduino IDE in conjunction with the C language compiler.After laying a solid foundation of DSP theory and pertinent discussions on the main DSP software tools on the market, the book presents the following audio-based sound and DSP projects: Using an I²S-based digital microphone to capture audio sound Using an I²S-based class-D audio amplifier and speaker Playing MP3 music stored on an SD card through an I²S-based amplifier and speaker Playing MP3 music files stored in ESP32 flash memory through an I²S-based amplifier and speaker Mono and stereo Internet radio with I²S-based amplifiers and speakers Text-to-speech output with an I²S-based amplifier and speaker Using the volume control in I²S-based amplifier and speaker systems A speaking event counter with an I²S-based amplifier and speaker An adjustable sinewave generator with I²S-based amplifier and speaker Using the Pmod I²S2 24-bit fast ADC/DAC module Digital low-pass and band-pass real-time FIR filter design with external and internal A/D and D/A conversion Digital low-pass and band-pass real-time IIR filter design with external and internal A/D and D/A conversion Fast Fourier Transforms (FFT)

ModbusRTU and ModbusTCP examples with the Arduino Uno and ESP8266 Introduction to PLC programming with OpenPLC, the first fully open source Programmable Logic Controller on the Raspberry Pi, and Modbus examples with Arduino Uno and ESP8266 PLC programming is very common in industry and home automation. This book describes how the Raspberry Pi 4 can be used as a Programmable Logic Controller. Before taking you into the programming, the author starts with the software installation on the Raspberry Pi and the PLC editor on the PC, followed by a description of the hardware. You'll then find interesting examples in the different programming languages complying with the IEC 61131-3 standard. This manual also explains in detail how to use the PLC editor and how to load and execute the programs on the Raspberry Pi. All IEC languages are explained with examples, starting with LD (Ladder Diagram) over ST (Structured Control Language) to SFC (Special Function Chart). All examples can be downloaded from the author's website. Networking gets thorough attention too. The Arduino Uno and the ESP8266 are programmed as ModbusRTU or ModbusTCP modules to get access to external peripherals, reading sensors and switching electrical loads. I/O circuits complying with the 24 V industry standard may also be of interest for the reader. The book ends with an overview of commands for ST and LD. After reading the book, the reader will be able to create his own controllers with the Raspberry Pi.

Based on PIC microcontrollers and Arduino Every mobile phone includes a GSM/GPRS modem which enables the phone to communicate with the external world. With the help of the GSM modems, users can establish audio conversations and send and receive SMS text messages. In addition, the GPRS modem enables users to connect to the internet and to send and receive large files such as pictures and video over the internet. This book is aimed for the people who may want to learn how to use the GSM/GPRS modems in microcontroller based projects. Two types of popular microcontroller families are considered in the e-book: PIC microcontrollers, and the Arduino. The highly popular mid-performance PIC18F87J50 microcontroller is used in PIC based projects together with a GSM Click board. In addition, the SIM900 GSM/GPRS shield is used with the Arduino Uno projects. Both GSM and GPRS based projects are included in the e-book. The book will enable you to control equipment remotely by sending SMS messages from your mobile phone to the microcontroller, send the ambient temperature readings from the microcontroller to a mobile phone as SMS messages, use the GPRS commands to access the internet from a microcontroller, send temperature readings to the cloud using UDP and TCP protocols and so on. It is assumed that the reader has some basic working knowledge of the C language and the use of microcontrollers in simple projects. Although not necessary, knowledge of at least one member of the PIC microcontroller family and the Arduino Uno will be an advantage. It will also be useful if the user has some knowledge of basic electronics.
