Paso 4: Conseguir empezar con la biblioteca de FastLED y subir el Arduino Sketch
Principalmente trabajo con la Biblioteca de FastLED.io para la programación de LED, es bastante fácil cuando se trata de programación RGB, y gran documentación para su código.
Aquí le damos un instructivo que detalla la instalación de la biblioteca de FastLED.
Este es el código que necesita para subir en el Arduino:
