Le jeu que nous allons créer est un Tetris.
Introduction
Pour mener à bien le projet, nous allons le réaliser en 2 étapes : la maquette, ainsi que la version finale.
La première maquette sera réalisée à partir de carton, et la version finale sera faite en bois avec des découpes laser.
Nous nous sommes répartit différentes tâches dans le groupe pour pouvoir avancer plus vite. Les différentes parties sont la programmation,l’électronique, ainsi que la mécanique. Pour la réalisation de la documentation nous avons chacun écris ce que l'on a fais.
outil et matériel
Le matériel nécessaire que l'on a à disposition est :
- Carte esp32 Wroom - plaque labdec - afficheur - Haut parleur - Panneau led 16x16 - interrupteur - joystick - Df mini mp3

étapes de fabrication
indiquer autant d'étape que nécessaire, chacune illustrée par des images (phot, dessins, ...)
étape 1
Réalisation de la maquette.
Pour la maquette, on a récupéré un quadrillage pour les led d'un projet précédent. Nous l'avons entouré de carton pour le maintenir et pouvoir faire la première version.
Il aurait été inutile de faire un boitier en carton pour mettre les composants tels que le joystick ainsi que les boutons, car les composants sont les mêmes pour la version finale.
C'est pour cela que nous avons minimisé un maximum la version de maquette.
Voici la maquette :
étape 2
On s'intéresse ensuite à la conception mécanique de notre structure. On a pensé à réaliser un écran ainsi qu'un tableau de bord avec le joystick et les boutons.
Pour la conception, on utilise Solidworks. On a au final ce modèle :
On utilisera une découpe laser pour que ce soit plus rapide et moins risqué à imprimer.
Voici les découpes :
étape 3
En parallèle, on s'occupe aussi de la programmation. On utilisera le code présenté précédemment.
Pour la partie électronique, on a testé plusieurs composants tels que le joystick pour savoir quel câble correspondait à quelle direction. Nous avons aussi fait marcher en premier la carte Arduino.Les boutons ainsi que le registre ont été testés pour bien comprendre leur fonctionnement.
On a donc implémenté chacun des composants nécessaires au fur et à mesure, tout en câblant sur la plaque labdec. Il faut bien prendre en compte les résistances de pull-up dans le montage, elles sont indispensables pour le bon fonctionnement des composants à faible résistance, tels que le bouton et le joystick.
On a donc le montage suivant ensuite :
Remarque : il est important de détailler chacun des fils en mettant des bouts de scotch pour décrire l’utilisation des fils. Par exemple, mettre "droite" pour le fil qui gère la droite du joystick, cela nous permettra de ne pas faire d'erreur de câblage.
Voici la première fois que l'on a pu jouer au jeu :
étape 4
Montage comlet

Un des problèmes majeurs que l'on a rencontré est l'absence de résistance de pull-up. En effet, ces résistances servent à bien déterminer le niveau haut et le niveau bas, pour que l'on ne connecte pas le 5v à la masse si le composant à une faible résistance. Donc pour les composants tels que les boutons ainsi que le joystick il faut mettre des résistances de pull-up.
