Stap 4: Aan de slag met de FastLED bibliotheek en uploaden van de schets van de Arduino
Ik werk vooral met de FastLED.io bibliotheek voor het programmeren van de LED, het is vrij moeiteloos als het gaat om RGB-programmering, en ze geweldige documentatie voor hun code hebben.
Hier is een instructable detaillering van de installatie van de bibliotheek FastLED.
Dit is de Code die nodig hebt om te uploaden naar de Arduino:
