Programming the Finite State Machine with 8-Bit PICs in Assembly and C
Andrew Pratt provides a detailed introduction to programming PIC microcontrollers, as well as a thorough overview of the Finite State Machine (FSM) approach to programming. Most of the book uses assembly programming, but do not be deterred. The FSM gives a structure to a program, making it easy to plan, write, and modify. The last two chapters introduce programming in C, so you can make a direct comparison between the two techniques. The book references the relevant parts of the Microchip datasheet as familiarity with it is the best way to discover detailed information.
This book is aimed at Microsoft Windows and Linux users. To keep your costs to a minimum and to simplify the toolchain, specific applications are provided as a free download to enable you to use an FTDI serial lead as the programmer. The assembler used is the open-source "gpasm". All programming can be done in a text editor. There are detailed instructions on how to perform the necessary installations on Windows, Linux Debian, and derivatives such as Ubuntu and Fedora. For programming in C, Microchip's XC8 compiler is used from the command line. In addition to the programming applications, two serial read and serial write applications can be used for communicating with the PICs from a computer.
A voltmeter project including practical instructions on building a circuit board from scratch is included. All theory is covered beforehand, including how to do integer arithmetic in assembly.
Two PICs are covered: the PIC12F1822 and the PIC16F1823. Both can run at 32 MHz with an internal oscillator. You do not need to buy a factory-made development board and programmer. With relatively inexpensive parts including a serial lead, microcontroller, a few resistors, and LEDs, you can get started exploring embedded programming.

The book is split into two parts: the first part covers creating Alexa skills and the second part, designing Internet of Things and Smart Home devices using a Raspberry Pi.
The first chapters describe the process of Alexa communication, opening an Amazon account and creating a skill for free. The operation of an Alexa skill and terminology such as utterances, intents, slots, and conversations are explained. Debugging your code, saving user data between sessions, S3 data storage and Dynamo DB database are discussed.
In-skill purchasing, enabling users to buy items for your skill as well as certification and publication is outlined. Creating skills using AWS Lambda and ASK CLI is covered, along with the Visual Studio code editor and local debugging. Also covered is the process of designing skills for visual displays and interactive touch designs using Alexa Presentation Language.
The second half of the book starts by creating a Raspberry Pi IoT 'thing' to control a robot from your Alexa device. This covers security issues and methods of sending and receiving MQTT messages between an Alexa device and the Raspberry Pi.
Creating a smart home device is described including forming a security profile, linking with Amazon, and writing a Lambda function that gets triggered by an Alexa skill. Device discovery and on/off control is demonstrated.
Next, readers discover how to control a smart home Raspberry Pi display from an Alexa skill using Simple Queue Service (SQS) messaging to switch the display on and off or change the color.
A node-RED design is discussed from the basic user interface right up to configuring MQTT nodes. MQTT messages sent from a user are displayed on a Raspberry Pi.
A chapter discusses sending a proactive notification such as a weather alert from a Raspberry Pi to an Alexa device. The book concludes by explaining how to create Raspberry Pi as a stand-alone Alexa device.

Design IoT Projects with Raspberry Pi, Arduino and ESP32 The Internet of Things (IoT) is becoming a major application area for embedded systems. As a result, more and more people are becoming interested in learning about embedded design and programming. Technical colleges and universities are moving away from legacy 8 and 16-bit microcontrollers and are introducing 32-bit embedded microcontrollers to their curriculums. Many IoT applications demand precision, high processing power, and low power consumption. Produced by IBM, Node-RED is an open-source visual editor for wiring the Internet of Things. Node-RED comes with a large number of nodes to handle a multitude of tasks. The required nodes are selected and joined together to perform a particular task. Node-RED is based on flow type programming where nodes are configured and joined together to form an application program. There are nodes for performing complex tasks, including web access, Twitter, E-mail, HTTP, Bluetooth, MQTT, controlling GPIO ports, etc. One particularly nice aspect of Node-RED is that the programmer does not need to learn how to write complex programs. For example, an email can be sent by simply joining nodes together and writing only a few lines of code. The aim of this book is to teach how Node-RED can be used in projects. The main hardware platform used with most of the projects in this book is Raspberry Pi 4. Chapters are included to show how Node-RED can be also be used with Arduino Uno, ESP32 DevKitC, and the ESP8266 NodeMCU microcontroller development boards.

From Detector to Software Defined Radio
Radio frequency (RF) technology is one of the areas which still allows putting your own ideas into practice. Countless circuit variants with special objectives allow space for meaningful experiments and projects. Many things simply aren’t available off the shelf. Crystal detector radios without their own power source, simple tube receivers with a touch of nostalgia, the first reception attempts at Software Defined Radio, special receivers for amateur radio, all this can be realized with little effort and as a perfect introduction to RF electronics.
For a long time, radio construction was the first step into electronics. Meanwhile, there are other ways, especially via computers, microcontrollers, and digital technology. However, the analog roots of electronics are often neglected. Elementary radio technology and easy-to-do experiments are particularly well suited as a learning field for electronics because you can start with the simplest basics here.
But the connection to modern digital technology is also obvious, for example, when it comes to modern tuning methods such as PLL and DDS or modern DSP radios.
This book aims to give an overview and present a collection of simple RF projects. The author would like to support you to develop your own ideas, to design your own receivers and to test them.

An important feature of the Raspberry Pi 3 is that it contains on-board Bluetooth and Wi-Fi modules. Example projects are given in the book on using the Wi-Fi and the Bluetooth modules to show how real-data can be sent to the Cloud using the Wi-Fi module, and also how to communicate with an Android based mobile phone using the Bluetooth module.
The book is ideal for self-study, and is intended for electronic/electrical engineering students, practising engineers, research students, and for hobbyists. It is recommended that the book should be followed in the given Chapter order.
Over 30 projects are given in the book. All the projects in the book are based on the Python programming language and they have been fully tested. Full program listings of every project are given in the book with comments and full descriptions. Experienced programmers should find it easy to modify and update the programs to suit their needs.
The following sub-headings are given for each project to make it as easy as possible for the readers to follow the projects:
Project title
