How to use LED Row with Arduino?

I have LED row like this web http://learn.adafruit.com/12mm-led-pixels/ but it have no datasheet. I don't know what it call, if I search LED in google it only show LED 2 pin. This LED row have 3 line which I think 1 line is ground and 2 line is serial. I try to test with this code http://learn.adafruit.com/12mm-led-pixels/code but LED not light. how to use LED Row with Arduino . please help me.

It will be impossible to give you more information without more information about what you have. Can you post some clear close-up pictures of your LED row?

This is the picture of my LED. I don’t know what it call and how to use with arduino.

No, with three lines 1 is ground, 1 is +5V and 1 is serial.

They might be WS2811 lights: https://www.insomnialighting.com/products/rgbpxws2811.html

The pictures aren't really clear enough. It looks to me like there might be 4 wires between lights (Red, White, Green, Blue). In that case the ones that aren't Power and Ground might be Data and Clock.

The last light even seems to have FIVE wires: Red, White, Green, Blue, Blue.

If I had to guess I would say:

Red: +5V White: Data Green: Clock Blue: Ground

This explains the flying leads for power and the three-lead connector for the Arduino (Ground, Data, Clock)

Did you try the wiring on this page: http://learn.adafruit.com/12mm-led-pixels/wiring (Use your White in place of their Yellow)
