Hi guys,
I’m pretty new to Arduino in general and recently got the 32 LED digital addressable strip listed here:

I followed the guide listed in the code here:

and tried to connect it to my Arduino Uno Rev 3. I made sure I connected everything to the 4 pin connector at the base of the arrows, as shown in the following two images (sorry all the wires are the same color. This is how it is set up: blue wire (5v) goes to 5v on the Arduino, black wire (Gnd) goes to ground on the Arduino, red wire (SDI-in) goes to port 2 on the Arduino, green wire (CKI-in) goes to port 3 on the Arduino. http://desmond.imageshack.us/Himg600/sc … res=medium

I then upload the example code and nothing happens. However, if I disconnect the ground wire from the Arduino, the very first led turns red.
I know I’m supposed to power it with a 5V 2A power source (I have one), but the same thing happens when it’s powered through it and the example code says USB power should be sufficient.
What am I doing wrong?
