bonjour à tous,

je vous écris aujourd'hui pour que vous m'aidiez sur mon problème je suis en 1ere S et je dois réaliser un TPE

sur la réalité virtuelle j'ai donc entrepris cette expérimentation : https://www.youtube.com/watch?v=J5_qsLDnqKE

le montage électronique a été réussie parfaitement mais lors du téléversement du code une erreur s'affiche dans la console

Arduino : 1.8.4 (Windows 10), Carte : "Arduino Leonardo"

Le croquis utilise 16520 octets (57%) de l'espace de stockage de programmes. Le maximum est de 28672 octets.
Les variables globales utilisent 544 octets (21%) de mémoire dynamique, ce qui laisse 2016 octets pour les variables locales. Le maximum est de 2560 octets.

avrdude done.  Thank you.

 n'existe pas ou votre Arduino n'est pas connectée

j'utilise une arduino uno R3 de selectronic.

merci de m'accorder votre aide.
