NeoPixel - WS2812 plugin

RGB Led op de Nodo Small? Kost je normaal drie PWM pinnen per LED. Behalve als je de WS2812 LEDs gebruikt, zoals o.a. in gebruik bij de "Adafruit Neopixel". Deze kun je op 1 digitale pin aansluiten en daarmee 1 of meerdere RGB leds aansturen, b.v.:

De plugin is wat code betreft zo compact mogelijk gehouden, waardoor deze ook op de Nodo Small toepasbaar is. Het RAM geheugen is hier wel beperkt, dus daarmee ook het aantal leds dat je maximaal kunt aansturen. Bovenstaande strip van 8 LEDs zal geen probleem zijn.

Werkt als een speer!! Getest met een paar losse leds. Bied een hoop mogelijkheden in ieder geval !

Denk dat je daarvoor te weinig lichtopbrengst hebt met een paar van deze ledjes, denk slimmer om 3 wat zwaardere led's daarvoor te gebruiken. Je hebt maar 3 kleuren nodig denk ik, RGB.
