Retour sur l'atelier Journal lumineux Récup'
Retrouvez ci-dessous la recette du Journal lumineux Récup' réalisé au cours de l'atelier MédiaLab du 28 mai 2022.
Au cours de cette séance, les participants ont pu réaliser un journal lumineux personnalisable et programmable à base d'électronique et de matériaux de récupération. Un bon prétexte pour s'initier au montage électronique et à la programmation à l'aide d'une carte Arduino.
Le résultat en vidéo en cliquant ici.
