Introduction

Le baromètre sonore capte le bruit (dans une classe par exemble) et allume un smiley en fonction de l'intensité du son.

Matériaux

Carte Arduino

Résistances

Ampoules LED

Transistor

Plexiglass

Bois

Outils

Découpe laser

Découpe vinyle

Fer à souder

Colle chaude

Barometre Sonore Code Arduino.odt

Étape 1 - Idéation

S'accorder ensemble sur le projet - imaginer d'abord séparément puis mettre en commun.

Baromètre sonore ideation 2.jpg

Étape 2 - Choix de l'échelle

Plusieurs projets sont débattus.

Baromètre sonore plan en pdf 2.jpg


Étape 3 - Construction d'une maquette

Un modèle en carton en trois dimension est construit pour prouver que le concept est possible.

Baromètre sonore poc.jpg



Étape 4 - Electronique Arduino

Construire le boitier électronique avec Arduino (hardware).

Baromètre sonore montage 1.jpg

Étape 5 - Programmation du code

Développer le programme informatique, d'abord sur le tableau puis sur l'ordinateur (software).

Étape 6 - Découpe laser

Utiliser une machine laser pour découper les parties de la boîte.

Ensuite, découper les cercles de couleur dans du plexiglas.

moins de 45 secondes de découpe par planche

Étape 7 - Assemblage de la boite

Assembler la boîte et la fixer à la colle chaude.




Étape 8 - Fixation des LED

Coller le circuit électronique, avec boitier Arduino et LED.

Étape 9 - Résultat final

Et maintenant, faites du bruit !
