Grumpy_Mike: What I am trying to see is if the LED is wired correctly. In order to do this I need to see the orientating mark on your LED. This is not viable in the added photograph. Also I can't see any 0.1uF ceramic capacitor across the power lines of the LED.
You changed your first post making my comment look silly. We don't like that round here. Please read this:- How to use this forum it will tell you how we like to play things here.
My bad about editing the post.
The orientation mark is on the corner with the black wire going to ground. Red is 5v. Yellow is Data on Pin 6.
Is the capacitor necessary to drive a single LED? I was reading that this was to prevent flickering when using several of these in a chain.
