Array of Char array

Bonjour,

Je sèche sur un problème Arduino et je ne sais pas comment/où trouver une solution.
J'ai une liste de variables que j'aimerais mettre dans un tableau de manière à pouvoir choisir aléatoirement un des éléments du tableau.

Comment créer un tableau avec ces valeurs et comment passer un élément du tableau à la fonction?

Code:
