Pas directement, non.

Des cordes de harpe en boyau ne sont pas de bons conducteurs électriques, donc elles ne feront pas une bonne électrode directe pour un contrôleur tactile capacitif. Le composant de ton projet est bien un capteur de toucher/proximité capacitif, donc il attend une électrode conductrice à son entrée . Et pour ce type de part, la règle est d’utiliser le datasheet comme source de vérité pour son interface et ses entrées .

En pratique :

corde en boyau pur -> non, ça ne convient pas comme électrode
corde métallique -> oui, beaucoup mieux
corde boyau + fil métallique caché / feuille cuivre / peinture conductrice -> oui, possible
corde filée métal -> possiblement oui, si la couche extérieure est bien conductrice et accessible

Le plus important à comprendre :

ce capteur ne cherche pas “du son”
il cherche une variation de capacité sur une surface conductrice
si la corde est isolante, ton doigt ne “parle” pas correctement à l’entrée

Donc pour une harpe tactile, le plus sûr est :

soit utiliser des cordes métalliques
soit garder l’esthétique boyau mais ajouter une électrode conductrice parallèle à chaque corde

Si tu veux, je peux te proposer 3 façons concrètes de faire une harpe tactile avec aspect boyau.
