I seem to remember someone saying you need to hook up your data signal to both data line inputs. Did you try that?

Thank you but i have tried but it does not work
The only time it was lit in white was with the FIRSTLIGHT example but it is staying on
I do not need to change something in the .h or .ccp file

You need to connect your DATA pin from the Arduino to the DIN1 pin of the 1st pixel and DIN2 pin of 2nd pixel

@elhilali_abdelghani Did you ever get this working?

@Leon_Yuhanov On mine i have pos, neg, DI and FI - what does FI stand for? im having the same issue as you guys ,have tried bridging between pixel 1 and 2 but i still get nothing

@Anthony_Lombard So POS=+5v, NEG=GND, DI=Data IN, tihs is what you connect to your micro to send the pixels data. and FI=Secondary data out(this goes into the DI of the next pixel.
