I purchased a WS2812B 5050 RGB LED Strip from ebay (http://www.ebay.com/itm/121979001999?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT) and I'm trying to light it up to test and make sure it works. To do this I attached the red and green wires (which should be power and data) each to a 5v power supply and the black wire to ground. I attached them to the side with the arrow facing away from the plug since I think that's where I have to plug it in.
Since this is an individually addressable LED strip I assumed this would turn all the lights up white, but what happened is all the LEDS flashed for a fraction of a second the first time I plugged it in and then turned off. Since then I can't get the LEDS to turn back on. I'm wondering if I blew the strip, but it says it can support 5v so I don't know how. How would I go about just lighting up all the LEDS white(or just any color it doesn't really matter) on this individually addressable LED strip?
