LED light Ribbons

I bought these LED light ribbons to incorporate into my E-Textiles project. I wanted to code them with Arduino but I am having a few issues.

I am currently using a Adafruit Flora board.

I know the silver is the Cathode, and the copper is the anode, however I am having issues coding this in the Arduino program.

Has any one used there before or have any advice? Can these be coded or am I wasting my time?

Thanks.
