I'm sorry to have to ask a newbie question, but I have tried everything else and I don't know what else to do.
I am trying to put together this instructables project:
I have two strings of these lights:
I have attached the Green data wire to pin 6 as instructed, and the white ground wire to GND on the Arduino Uno board.
I have all the drivers etc on my computer and have uploaded a Blink sketch to the Uno board, and this works, albeit fairly faintly.
This is the only thing I can actually make happen and none of the other examples will light up anything else.
I have tried adding extra power, but if I plug in the other end of the lights they all just come on bright white. The same happens if I try to connect the 5v cable to my uno, or power the uno using a seperate power source.
I have tried gooling and trawling through youtube videos and no matter how many I follow, I appear to be doing the right thing but nothing is working.
Help! What am I missing?
