Avec la librarie FastLED et quelques LED RGB Adressable (RB-Spa-967), on obtient des effets de lumieres interressants.
L’exemple ici est LEDStrip Effect – Snow Sparkle, mais a cette adresse on peux trouver plein d’autres exemples
Matériel
- LED Adressable – RB-SPA-967
- Arduino UNO compatible – RB-DFR-189
