Rédation en cours ….

Pour des besoins personnels, j’ai eut envie de me créer un petit clavier avec uniquement les touches de fonctions importantes de Sketchup.

Mon choix va donc naturellement se porter vers une carte a base d’Atmega32u4, Arduino leornado, Arduino micro, ou une copie chinoise de préférence de petite taille …

Le clavier 4×4 de Robotdyn as le bon goût de ne nécessiter que 3 fils de connexion !
Une masse, un +5V, et une broche analogique, dans mon cas la N° 3.

Un exemple de raccourcis pour Sketchup:

Câblage, 3 fils a connecter !

Ca fonctionne parfaitement 🙂
