might be connected to wrong end of strip (the end wires, if A working strip will show a few pixels moving down the line, to GND FIRST, then +5V and digital pin 6, then re-plug USB. So upload code first, unplug USB, connect pixels may nonetheless hiccup when LEDs are first connected and not 1m strip can safely be powered from Arduino 5V pin.

Wiring to arduino (only had red wire at the end, so the black one off the screen is going to the '-' on the strip. Is there something I'm missing or is this wire defective? I believe that it should be wired correctly, and that the correct side of the strip is being used. I also tried my own code I wrote for it, but it was impossible to actually figure out whether that would be working as intended since only the first pixel seems to work. It seems like its 'working', except only for the first pixel. However, instead of doing the intended action (a line of pixels traveling down the strip), only the first pixel lights up (as evidenced here ). On using the same code from before (from. I wired up this NeoPixel skinny strip to my Arduino Uno.
