Este libro surge a raíz de la necesidad de crear un compendio de prácticas para iniciar a alumnos de formación profesional de grado medio, grado superior y bachillerato a la robótica y a la domótica mediante Arduino (Description in English below). La estructura del libro permite diferenciar tres partes: el primero dedicado a exponer unos conceptos sobre Arduino y las disciplinas que lo rodean; el segundo dedicado a la explicación del lenguaje de programación de Arduino; y el tercero dedicado al aprendizaje de Arduino a través de prácticas, donde el lector va aprendiendo cómo manejar la placa Arduino para crear sus propios proyectos. Description in English: This book arises from the need to create a compendium of practices to initiate vocational students of intermediate, higher and baccalaureate degrees to robotics and home automation through the Arduino platform. The structure of the book allows to differentiate three parts or blocks: the first one dedicated to expose a few concepts about Arduino and the disciplines that surround it; the second dedicated to the explanation of the Arduino programming language; and the third block is dedicated to the learning of Arduino through a series of practices, where an electronic component or sensor is exposed. Each practice has the code fully explained, commented and analyzed.This book proposes a series of 28 detailed and commented practices to teachers that wish to incorporate Arduino in some of their subjects, and of reference and learning guide for those readers that can be considered new in Arduino.Therefore, the reader learns through practices, isolated in appearance, how to handle the Arduino board and then create their own projects.
