I recently received at
5m lpd8806 digital LED strip, and have been having a problem with the entire strip lighting. The wires are all soldered and connected properly, as the majority of the strip is responding perfectly. The last 0.5 meter however, does not light at all. Originally it the entire strip functioned normally when I ran the strandtest example in Arduino IDE. I am only using a 2A power supply, could this be the issue? From what I read in the adafruit tutorial it seems that if the strip was not powered fully, the ending LEDs would still light up albeit not the correct colors.
