Bonjour,

Grand novice, je n'arrive pas à résoudre ce blocage, j'essaies de programmer une voiture façon IoT avec Blynk en utilisant le code ci-dessous, j'ai la carte dev ESP32 D1 R32, sur Arduino IDE elle est connecté sur DOIT ESP32 DEVKIT V1.

}

Quand je compile j'ai l'erreur suivant

exit status 1
'analogWrite' was not declared in this scope




Merci d'avance pour toute aide.
