Bonjour,

Je suis en terminale et pour notre projet de fin d'année, nous avons choisis de créer une serrure biométrique avec Arduino. Maintenant, je voudrais ajouter un contrôle bluetooth, c'est à dire que, lorsque le moteur ne tourne pas, il soit possible d'ouvrir la porte avec le mot "Ouvrir" envoyé depuis le téléphone. J'utilise le module Serial Bluetooth de Grove.
Maintenant, après de nombreuses heures d'essais, je n'ai toujours pas trouvé pourquoi le programme ne fonctionne pas. A ce stade, j'essaie juste de faire apparaître les mots entrés dans le téléphone dans la console.
Quelqu'un pour m'aider ?
Merci d'avance
