{{Introduction
−
|Introduction=Créer une guitare électrique et autonome, à moindre coût, que les participants peuvent rapporter chez eux à la fin de l'activité.
+
|Introduction=Le but de ce tutoriel est d'assembler une station météo équipée pour afficher la température, l'humidité et la concentration en gaz nocifs.
  
−
Inspirée de l'instrument de musique appelé thérémine.
+
Cette station se veut simple d'utilisation et réalisable à bas coût.

Une fois cela fait, utiliser le code ci-dessus qui permet de récupérer les données envoyées par les capteurs et de les afficher sur l'écran de la carte :

Pour une utilisation plus complète de la carte Heltech, se reporter au schéma suivant qui explique plus en détails le rôle des différents PINS :

Le haut -parleur est préparé en soudant, à chaque sortie, un fil dupont dont l'extrémité femelle est libre. Sur une de ces extrémités, brancher une des fiches extérieures du potentiomètre. Sur la fiche du milieu, brancher un fil dupont femelle-femelle.

Introduction

Le but de ce tutoriel est d'assembler une station météo équipée pour afficher la température, l'humidité et la concentration en gaz nocifs.

Cette station se veut simple d'utilisation et réalisable à bas coût.
  • Fichiers
Breadboard
Item-Breadboard 300px-Cspa 1.jpg
L'avantage de ce système est d'être totalement réutilisable, car il ne nécessite pas de soudure. Ce dernier point distingue les platines Labdec des stripboards (ou veroboards), des perfboards ou des circuits imprimés qui sont, eux, utilisés pour réaliser des prototypes permanents et que l'on sera donc moins à même de démonter. On peut de plus câbler sur une platine Labdec une grande variété de composants afin de réaliser des circuits électroniques, du plus simple circuit jusqu'au microprocesseur.

Un super outil pour la bidouille électro-technique !

Arduino est un circuit imprimé qualifié de libre et open-source (les plans sont consultables et tout le monde peut fabriquer une copie exacte de l'Arduino, contrairement à la plupart des objets manufacturés de notre environnement comme les machines à laver, les téléphones, les ordinateurs). Seuls le nom et le logo sont réservés.

Sur Arduino se trouve un microcontrôleur (calculateur) qui peut être programmé pour analyser et produire des signaux électriques.

En gros, on y branche des capteurs, le programme de l'Arduino traite les informations données par le capteur et déclenche des actions (comme allumer ou éteindre, augmenter, diminuer...).

Il peut être utilisé pour effectuer des tâches très diverses comme la charge de batteries, la domotique (le contrôle des appareils domestiques (éclairage, chauffage...), le pilotage d'un robot, etc.

Arduino peut être utilisé pour construire des objets interactifs indépendants (prototypage rapide), ou bien peut être connecté à un ordinateur pour communiquer avec ses logiciels. Plusieurs versions

Il existe plusieurs versions de l'Arduino officiel, plus des versions réalisées par d'autres constructeurs.

Sur wikidébrouillard, nous utiliserons en général l'Arduino Uno.

Fil électrique
Item-Fil électrique 179px-Stranded lamp wire.jpg
Un fil électrique : est le composant électro technique servant au transport de l'électricité, afin de transmettre de l'énergie et de l'information. Il est constitué d'un matériau conducteur, mono-brin ou multi-brin, souvent entouré d'une enveloppe isolante (plastique, Téflon...). L'intérieur du fil électrique est appelée « âme » du fil.

Le terme anglais Universal Serial Bus ou USB (en français bus universel en série) est une norme relative à un bus informatique en série qui sert à connecter des périphériques informatiques à un ordinateur ou à tout type d'appareil prévu à cet effet (tablette, smartphone, etc.).

Étape 1 - Placer la carte sur la Breadboard

Après avoir soudé la carte à une embase à broches, la placer sur la Breadboard.

Étape 2 - Connecter les capteurs à la carte

Une fois la carte placée sur la Breadboard, les 2 capteurs se connectent de la façon suivante (voir schéma).

Étape 3 - Téléverser le code de la station météo

Connecter la carte à l'ordinateur en utilisant un câble USB / micro USB.


Une fois cela fait, ouvrir le logiciel Arduino et télécharger la bibliothèque correspondant au capteur DHT 22 et compatible avec la carte Heltech : DHTesp.


Une fois cela fait, utiliser le code ci-dessus qui permet de récupérer les données envoyées par les capteurs et de les afficher sur l'écran de la carte : Pour une utilisation plus complète de la carte Heltech, se reporter au schéma suivant qui explique plus en détails le rôle des différents PINS :

Étape 4 - Préparer l'alimentation de la station météo

La station fonctionne au moyen d'une batterie 18650 que l'on installe sur un support.


Connecter la sortie 5 Volts de ce support à la borne 5V de la carte Heltech sur la Breadboard.


Remarque : on peut également utiliser d'autres batteries

Étape 5 - Construire le boîtier de la station météo

Le plus simple est d'opter pour une boîte en carton parallélépipédique.


Avec le matériel décrit sur cette page, les dimensions étaient celles décrites sur la photo du patron.




Étape 6 - Placer les éléments dans le support

Comment ça marche ?

Observations : que voit-on ?

La station permet d'afficher
