Initial connection - 5V LED strip
I used the same strip and  looks good. Few things you should keep in mind. Each chip with LED consume on max current
60 mA. But so big current cannot pass via ribbon. At least connect power 5V from both sides. Even somethere in the middle,if you plans to use it close to maximum.  Minimum consumption one chip less then 1mA. Two plugs, second for connecting next string. The first plug to connect controller find by marking on ribbon. Green wire to DIN. Power you may connect any side. About controller, I didn't deal. Just used PIC MC
