Ok, thanks DrAzzy.
As for actually powering these LED's, I understand that I can't rely on the power coming from Espruino as the LED's need more juice. There are separate red and black wires going into this thing which I presume is the power - could you please recommend a power supply I could purchase for this (and other similar electronic components)? Wall plug or from USB, anything really, I don't know where to start!
