STM32 Nucleo family of processors are manufactured by STMicroelectronics. These are low-cost ARM microcontroller development boards. This book is about developing projects using the popular STM32CubeIDE software with the Nucleo-L476RG development board. In the early Chapters of the book the architecture of the Nucleo family is briefly described.The book covers many projects using most features of the Nucleo-L476RG development board where the full software listings for the STM32CubeIDE are given for each project together with extensive descriptions. The projects range from simple flashing LEDs to more complex projects using modules, devices, and libraries such as GPIO, ADC, DAC, IC, SPI, LCD, DMA, analogue inputs, power management, X-CUBE-MEMS1 library, DEBUGGING, and others. In addition, several projects are given using the popular Nucleo Expansion Boards. These Expansion Boards plug on top of the Nucleo development boards and provide sensors, relays, accelerometers, gyroscopes, Wi-Fi, and many others. Using an expansion board together with the X-CUBE-MEMS1 library simplifies the task of project development considerably.All the projects in the book have been tested and are working.

Los métodos estadísticos son una parte fundamental de la ciencia de datos, pero pocos científicos de datos tienen una formación avanzada en estadística. Los cursos y libros sobre estadística básica rara vez tratan el tema desde la perspectiva de la ciencia de datos. La segunda edicion de este libro incluye ejemplos detallados de Python, ofrece una orientacion practica sobre la aplicacion de los metodos estadisticos a la ciencia de datos, te indica como evitar su uso incorrecto y te aconseja sobre lo que es y lo que no es importante.Muchos recursos de la ciencia de datos incorporan metodos estadisticos, pero carecen de una perspectiva estadistica mas profunda. Si estas familiarizado con los lenguajes de programacion R o Python y tienes algun conocimiento de estadistica, este libro suple esas carencias de una forma practica, accesible y clara.Con este libro aprenderas:Por que el analisis exploratorio de datos es un paso preliminar clave en la ciencia de datosComo el muestreo aleatorio puede reducir el sesgo y ofrecer un conjunto de datos de mayor calidad, incluso con Big DataComo los principios del diseño experimental ofrecen respuestas definitivas a preguntasComo utilizar la regresion para estimar resultados y detectar anomaliasTecnicas de clasificacion esenciales para predecir a que categorias pertenece un registroMetodos estadisticos de aprendizaje automatico que "aprenden" a partir de los datosMetodos de aprendizaje no supervisados para extraer significado de datos sin etiquetarPeter Bruce es el fundador del Institute for Statistics Education en Statistics.com.Andrew Bruce es cientifico investigador jefe en Amazon y tiene mas de 30 años de experiencia en estadistica y ciencia de datos.Peter Gedeck es cientifico de datos senior en Collaborative Drug Discovery, desarrolla algoritmos de aprendizaje automatico para pronosticar propiedades de posibles futuros farmacos.

A remarkable fact in mathematics is the accordance between algebra and geometry: since the time of Descartes it is possible to express geometric phenomena in terms of numbers. And after doing calculations with these numbers, we can draw geometric conclusions from them. However, soon it appeared that, for instance, a circle and a line outside that circle have imaginary meeting points: points that have imaginary coordinates but can not be found in the figure. Karl von Staudt found a brilliant way to visualize imaginary geometric points, lines and planes, and Felix Klein simplified and extended his method. In this book imaginary elements appear as Klein-movements in our real space. Apart from its mathematical importance, these movements may be seen as an alternative for the remarkable occurrences of complex numbers in physics, viz. quantum physics.

This book will take you on a whirlwind tour of full-stack web application development using Raspberry Pi. You will learn how to build an application from the ground up.You will gain experience and know-how of technologies including:- The Linux operating system and command line.- The Python programming language.- The Raspberry Pi General Purpose Input Output pins (GPIOs).- The Nginx web server.- Flask Python web application microframework.- JQuery and CSS for creating user interfaces.- Dealing with time zones.- Creating charts with Plotly and Google Charts.- Data logging with Google Sheet.- Developing applets with IFTTT.- Securing your application with SSL.- Receiving SMS notifications to your phone using Twilio.This book will also teach you how to set up a remote wireless Arduino sensor node and collect data from it. Your Raspberry Pi web application will be able to process Arduino node data in the same way it processes data from its onboard sensor.Raspberry Pi Full Stack will teach you many skills essential to building Web and Internet of Things applications.The application you will build in this project is a platform that you can extend upon.

Ever since the Raspberry Pi was introduced, it has been used by enthusiasts to automate their homes. The Raspberry Pi is a powerful computer in a small package, with lots of interfacing options to control various devices. This book shows you how you can automate your home with a Raspberry Pi. Youll learn how to use various wireless protocols for home automation, such as Bluetooth, 433.92 MHz radio waves, Z-Wave, and Zigbee. Soon youll automate your home with Python, Node-RED, and Home Assistant, and youll even be able to speak to your home automation system. All this is done securely, with a modular system, completely open-source, without relying on third-party services. Youre in control of your home, and no one else.At the end of this book, you can install and configure your Raspberry Pi as a highly flexible home automation gateway for protocols of your choice, and link various services with MQTT to make it your own system. This DIY (do it yourself) approach is a bit more laborious than just installing an off-the-shelf home automation system, but in the process, you can learn a lot, and in the end, you know exactly whats running your house and how to tweak it. This is why you were interested in the Raspberry Pi in the first place, right?- Turn your Raspberry Pi into a reliable gateway for various home automation protocols. - Make your home automation setup reproducible with Docker Compose. Secure all your network communication with TLS.- Create a video surveillance system for your home.- Automate your home with Python, Node-RED, Home Assistant and AppDaemon.- Securely access your home automation dashboard from remote locations.- Use fully offline voice commands in your own language.

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.
