manuel Buenos días Fernando. Efectivamente, necesitas "algo" que controle los leds ( arduino, raspberry o controladores específicos). Para eso están DI ( digital input) y DO (Digital Output). Cuando lo conectas a 5Vcc y Gnd, le falta que le indique qué quieres encender y cómo.Si lo quieres para "jugar" te recomiendo algo como:Controlador IR de 21 teclas LED Mini Dream Color para WS2812 WS2812B WS2811 Tira de luz DC5-24V.
