Il arrive souvent, lors de la programmation avec l’Arduino, que l’on doive convertir un float en string.
Arduino : Float to String – comment faire
Pour les instructions suivantes, nous partons du principe que vous avez déjà défini une variable float. Cela se fait par exemple avec la commande « float floatvariable = 12.4 ; ».
Pour assigner la chaîne de caractères du float à la variable string, il suffit d’exécuter la commande « Stringvariable = String(floatvariable) ; ».
Attention : lors de la déclaration, la chaîne doit être écrite avec une majuscule initiale.
Vous pouvez ainsi facilement convertir des nombres à virgule flottante en chaînes de caractères et les afficher par exemple sur un écran.
