Le kit satellite d'interaction vocale peut étendre la portée de votre station de base à chaque pièce de votre maison et vous permettre d'interagir avec le matériel en fonction de l'endroit où vous émettez vos commandes ! Vous pouvez disposer plusieurs kits satellite dans toute votre maison pour ajouter de nouvelles fonctionnalités au kit de base ou à tout autre haut-parleur intelligent, étendant ainsi votre commande vocale à plusieurs pièces.
Le kit satellite d'interaction vocale est alimenté par un Raspberry Pi Zero W et le ReSpeaker 2-Mics Pi HAT. Le kit comprend un haut-parleur, un capteur Grove – Temperature Humidity Sensor (SHT31), un relais Grove et un panneau perforé pour l'accrocher au mur ou créer un support astucieux.
Veuillez noter
Tous les kits satellite nécessitent un kit de base (lien vers le kit de base d'interaction vocale Snips) ou un Raspberry Pi pour fonctionner comme prévu.
Le kit DIY Mini Digital Oscilloscope (avec boîtier) est un kit facile à construire pour un minuscule oscilloscope numérique. Outre l'interrupteur d'alimentation, il ne comporte qu'une seule autre commande, un encodeur rotatif avec bouton-poussoir intégré. Le microcontrôleur du kit est préprogrammé. L'écran OLED de 0,96 pouces a une résolution de 128 x 64 pixels. L'oscilloscope dispose d'une voie qui peut mesurer des signaux jusqu'à 100 kHz. La tension d'entrée maximale est de 30 V, la tension minimale de 0 V.
Le kit se compose de composants à trous traversants (THT) et de dispositifs de montage en surface (SMD). Par conséquent, l'assemblage du kit implique de souder des pièces SMD, ce qui nécessite une certaine expérience en matière de soudure.

Learn programming for Alexa devices, extend it to smart home devices and control the Raspberry Pi
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.
Le kit de support de bricolage MicroMod comprend cinq connecteurs M.2 (hauteur 4,2 mm), des vis et des entretoises afin que vous puissiez avoir toutes les pièces spéciales dont vous pourriez avoir besoin pour fabriquer votre propre carte de support. MicroMod utilise le connecteur M.2 standard. C’est le même connecteur que l’on trouve sur les cartes mères et les ordinateurs portables modernes. Il y a divers emplacements pour la « clé » en plastique sur le connecteur M.2 pour empêcher un utilisateur d’insérer un dispositif incompatible. La norme MicroMod utilise la touche « E » et modifie la norme M.2 en déplaçant la vis de montage de 4 mm sur le côté. La touche « E » est assez courante pour qu’un utilisateur puisse insérer un module Wifi compatible M.2. Cependant, parce que le support à vis ne s’aligne pas, l’utilisateur ne sécuriserait pas un dispositif incompatible dans une carte de support MicroMod. Caractéristiques : 5x Vis mécaniques Tête cruciforme Phillips #0 (mais de #00 à #1 fonctionne également) Fil : M2.5 Longueur : 3 mm 5x Entretoises compatibles SMD Reflow Filetage : M2.5 x 0.4 Hauteur : 2,5 mm Connecteurs MicroMod 5x M.2 Clé : E Hauteur : 4,2 mm Nombre d’épingles : 67 Pas : 0,5 mm

Secure, Modular, Open-Source and Self-Sufficient
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. You’ll learn how to use various wireless protocols for home automation, such as Bluetooth, 433.92 MHz radio waves, Z-Wave, and Zigbee. Soon you’ll automate your home with Python, Node-RED, and Home Assistant, and you’ll 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. You’re 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 what’s 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.

Develop your own custom home automation devices
Espressif's ESP8266 and ESP32 microcontrollers have brought DIY home automation to the masses. However, not everyone is fluent in programming these microcontrollers with Espressif's C/C++ SDK, the Arduino core, or MicroPython. This is where ESPHome comes into its own: with this project, you don’t program your microcontroller but configure it.
This book demonstrates how to create your own home automation devices with ESPHome on an ESP32 microcontroller board. You’ll learn how to combine all kinds of electronic components and automate complex behaviours. Your devices can work completely autonomously, and connect over Wi-Fi to your home automation gateways such as Home Assistant or MQTT broker.
By the end of this book, you will be able to create your own custom home automation devices the way you want. Thanks to ESPHome and the ESP32, this is within everyone’s grasp.
Set up an ESPHome development environment and create maintainable configurations
Use buttons and LEDs
Sound a buzzer and play melodies
Read measurements from various types of sensors
Communicate over a short distance with NFC, infrared light, and Bluetooth Low Energy
Show information on various types of displays
