Description
Projets avec Arduino, ESPHome, Home Assistant, et Raspberry Pi & Co.
Ce livre électronique contient plusieurs exemples de projets, en commençant par une introduction à l'électronique. Il explique également comment installer Home Assistant sur un Raspberry Pi, comment utiliser des capteurs de climat intérieur pour la température et l'humidité, comment mettre en œuvre le protocole MQTT et d'autres interfaces, et comment utiliser ESPHome pour intégrer des capteurs et des actionneurs dans Home Assistant. De nombreux tutoriels vidéo complètent le livre.
Fundamentals of electrical engineering
The book begins with an introduction to electrical engineering. You will learn the basics of voltage, current, resistors, diodes and transistors.
Arduino and microcontrollers
A complete section is dedicated to the Arduino Uno. You will get to know the structure, write your first programs and work on practical examples.
Home Assistant and automation
You will learn how to set up Home Assistant on a Raspberry Pi and how to use automations, scenes and devices. In addition, Zigbee, MQTT and ESP-NOW – important technologies for home automation – will be discussed.
ESP8266, ESP32 and ESP32-CAM
The popular ESP microcontrollers are covered in detail. A theoretical introduction is followed by practical projects that show you how to get the most out of these devices.
Sensors and actuators
The book explains the functionality and application of numerous sensors such as temperature and humidity sensors, motion detectors and RFID readers. For actuators, stepper motors, e-ink displays, servo motors and much more are covered. There are practical application examples for all devices.
ESPHome
This chapter shows you how to integrate sensors and actuators into Home Assistant without any programming effort. You will be guided step by step through the setup with ESPHome.
LEDs and lighting technology
In this chapter, you will learn about different types of LEDs and how they can be used. The basics of lighting technology are also explained.
Node-RED
A whole chapter is dedicated to Node-RED. You will learn the basics of this powerful tool and be guided step by step through its setup and use.
Integrated Circuits (ICs)
In electronics, there are numerous ICs that make our lives easier. You will get to know the most important ones and apply your knowledge in practical projects.
Professional programming
Advanced topics such as the correct use of buttons, the use of interrupts and the use of an NTP server for time synchronisation are covered in detail in this chapter.
