Hello,
I keep getting only this single green light. Power source is 5V 2A. Any suggestions?
Do you have other parts to test against? Test the controller with another strip, and test the strip with another controller. My guess is you’ve got a bad connection or a bad pixel. The clip-on connectors aren’t great, but they come in handy for situations like this. Keep cutting off pixels until it starts working. Typically, if you mess something up by hooking it up wrong or even accidentally applying 12v, just the first pixel or two gets damaged.
