| − | Voici le shéma du circuit, il indique sur quels sorties/branchements les différents objets doivent être branchés. Pensez à utiliser des couleurs pour vous repérez:
| |
| − | | |
| − | | |
| − | Le rouge est le plus souvent dédié au 5V (le +)
| |
| − | | |
| − | Le Noir/marron/blanc au GND (Le -)
| |
| − | | |
| − | Les couleurs aux entrées numériques ( une information qui passe)
| |
| − | | |
| − | | |
| − | Si vous êtes assez aguéris, ce shéma peut vous suffire. Le reste du tutoriel essaye de donner un maximum de conseils :)

| − | Ce cable de connection femelle vous l'obtenez avec l'achat de votre guirlande.
| |
| − | | |
| − | Il peut être présent en bonus ou à découper au bout de la guirlande. (découpez bien le femelle!)
| |
| − | | |
| − | | |
| − | '''Image 3'''
| |
| − | | |
| − | | |
| − | Notre alimentation doit sortir de la boite. Je déconseille d'alimenter directement par la prise USB de l'arduino à l'usage. Risque de casser le branchement à force d'usage (sauf à coller le cable à la boite par exemple). Mais surtout, vous ne pourrez pas ajouter d'interrupteur comme sur le shéma. Je vous recommande donc :
| |
| − | | |
| − | | |
| − | - Une batterie à pile ou de type 18650 ( comme sur le shéma)
| |
| − | | |
| − | - Un vieux cable USB, assez long, que vous aurez dénudé (Cables rouge et noir)
| |
| − | | |
| − | | |
| − | '''Image 3'''
| |
| − | | |
| − | | |
| − | De même à l'usage, brancher les boutons directement à la carte est risqué ( mais toujours possible; pensez à coller les cables à la boite, ou faire un noeud) . Les participants tirent dessus, et risque de casser le branchement. Aussi, vous pouvez utiliser des "prises". Le branchement reste le même, et s'agissant de bouton, peut importe de quel coté vous branchez!

| − | |Step_Content=Le logiciel permettant de téléverser le code est disponible en ligne. Je vous le conseil largement. Aucun problème de compatibilité, plus simple à utiliser que le logiciel sur bureau. Il faut simplement un compte. | + | |Avertissement=Pour que l'expérience fonctionne au mieux, il faut réussir à obtenir une différence de température importante entre le début et la fin de l'expérience. Donc il est souhaitable de partir avec du matériel et de l'eau froids. Le temps pendant lequel la bougie brûle est aussi important : si elle s'éteint trop vite elle ne peut pas chauffer beaucoup l'ensemble. Ainsi il est plus efficace d'utiliser un contenant haut (mais pas trop volumineux) dans lequel il y a un volume d'air important (qui contient du dioxygène) au desssus de la bougie. Par exemple une bouteille en verre type jus de fruit et une bougie coupée de façon à ce qu'elle mesure la moitié de la hauteur de la bouteille fonctionne très bien. |
| − | https://create.arduino.cc/editor
| |
| | | | |
| | + | Dernier point. Quand on refait l'expérience plusieurs fois d'affilée, il faut trouver un moyen de renouveler l'air dans le bocal ou la bouteille. En effet le dioxygène qui était contenu dedans a été consommé et donc la bougie va s'éteindre très vite si il n'est pas renouvelé. |
| | + | |Explanations='''Lorsque tu couvre la bougie avec le verre il se passe deux choses :''' |
| | | | |
| − | Le code est lisible et disponible [https://create.arduino.cc/editor/zabern/eadfd3dc-693f-4161-bb39-d9aa35522e26/preview ICI]
| + | - D'une part, la combustion nécessite du dioxygène (O2) et produit du dioxyde de carbone (CO2). Lorsque la quantité de dioxygène présente dans le verre devient trop faible alors la flamme s'éteint. |
| | | | |
| | + | - D'autre part, la flamme de la bougie produit de la chaleur qui va chauffer l'air présent dans le verre. L'air en chauffant se dilate. C'est à dire que pour la même quantité d'air, cet air prend plus de place. On peut d'ailleurs constater cette dilation, car lorsque l'on pose le bocal sur la bougie, un bulle d'air s'échappe. |
| | | | |
| − | Le code contient une partie aisément modifiable avec les paramètres principaux.
| + | Lorsque la flamme s'éteint (du fait du manque d'oxygène) l'air refroidit. A l'inverse de la dilatation , en se refroidissant, l'air se rétracte, c'est à dire qu'il prend moins de place. L'eau va alors être aspirée dans le verre occupant la place ainsi libérée. |
| | + | |Deepen=Ce phénomène fait intervenir la loi des gaz parfaits, PV=nRT, avec : |
| | | | |
| | + | *P : la [https://fr.wikipedia.org/wiki/Pression pression] (Pa), |
| | + | *V : le [https://fr.wikipedia.org/wiki/Volume volume] du gaz (m<sup>3</sup>), |
| | + | *n : la [https://fr.wikipedia.org/wiki/Quantit%C3%A9_de_mati%C3%A8re quantité de matière] (mol), |
| | + | *R : la [https://fr.wikipedia.org/wiki/Constante_universelle_des_gaz_parfaits constante universelle des gaz parfaits] (≈ 8,314 J·K<sup>-1</sup>·mol<sup>-1</sup>), |
| | + | *T : la [https://fr.wikipedia.org/wiki/Temp%C3%A9rature_absolue température absolue] (K). |
| | | | |
| − | ''// Branchements''
| + | Dans notre cas, la quantité de mol (n) et la constante (R), ne varient pas. |
| | | | |
| | + | Dans un premier temps la température augmente, la production de gaz fait varier son volume mais vu que le verre garde le même volume, la pression augmente un petit peu. |
| | | | |
| − | ''#define MAXLED 300 // Nombre de leds (300 = 5m )'' | + | Puis lorsque la flamme s’éteint la température diminue et la rétraction de l'air devenu froid, fait diminuer le volume d'air et sous l'effet de la pression, l'eau est aspirée dans le verre et une fois l'eau dans le verre la pression redevient normal. |
| | + | |Applications=L'air chauffé dans la cocotte-minute est contenue sous pression lorsqu'elle est fermée et une fois le sifflet ouvert la pression diminue ce qui nous permet de l'ouvrir. |
