Intelligent Controll RGB LED OSTW5050C1A

Hello Community,

I just got 10 of those SMD RGB´s: http://www.optosupply.com/UploadFile/PDF/ostw5050c1a.pdf

I want to control them but I don´t realy understand how it works.
I already searched the Internet but I couldn´t find a tutorial for Intelligent Digital RGB´s.

Do I need to put a RGB´Controler between Arduino and the RGB´s or can I control them directly?;
How do I send them the datas of the colors that i want and first of all how do i create the datas? (only need red, green, yellow and blue);

It would be realy cool if somebody that has experience with this sort of RGB´s could explain it to me or send me a link to a good tutorial if you know one.

Greetings,

They look very similar to Neopixels and the place to look them up is here.
