Then someplace I read that the Data in and Data out labels are swapped. So, to get it to work connect the D out pin to the Arduino D6 pin. It came to LIFE! Then after about a minute smoke rose out of the Arduino. The voltage regulator had gone up in smoke. Find an 5 volt 1-2 amp AC adapter and use that to power the LED array.
Here is a picture of it running the Adafruit demo.
This is the back view showing how to connect it to the Arduino and to power.
This is the video of the demo.
