Étape 4: Code : Arduino
le code final peut être trouvé ici (veillez à ajouter des classes BinaryTree et nœud au fichier MorseCode.ino)
le code est divisé en 3 grandes étapes :
1 - basculer entre l’état de lecture et d’écriture état grâce à un bouton poussoir
2 - (écriture état) prendre une saisie de texte à partir du tableau et convertir une séquence de points et de tirets exprimées en lumière LED
3-(état de la lecture) surveiller la LDR pour entrée de lumière, faire la distinction entre point, tiret et l’espacement entre les lettres et les mots, une fois que j’ai une file d’attente de ma séquence de dot et tableau de bord que je veux utiliser un arbre binaire, à savoir la représentation de la lettre.
