12mm Diffused digital RGB LED pixels doesn't work for me

Post by Rongrong »

Hello,
I got a strand of 12 mm diffused digital RGB LED pixels and an Arduino Mega 2560. I am working on Mac OS Lion. I am trying to run the example code provided on the product page and adalight but none of them worked yet. 1) when i powered the strand up without connecting any other wires, only the last LED lit up. Is it normal? 2) When i connect the data and closck wires with pin 51 and pin 52 (i modified the datapin clockpin part in the code already) nothing shows up.

Is there something i did not correct? Please help. THanks!

never mind. I got it work now. The mistake i made is that data/clock input from the wrong side. The tutorial actually has emphasized this point :(
