MOST of the time the strip works fine, in fact it sometimes passes the sample color_test. However, whenever I go to really low brightness that specific strip goes all random-rainbowy-glowy at various sections of the strip. It will happen other times as well even with static light, but it almost always happens when I change the ambient light. I'm pretty sure the first pixel in the strip may be damaged but wanted to verify that and there's no way to save it (it's just weird that it works SOMETIMES).
If I do have to discard that one pixel, can I just solder OVER it? Keep positive and negative through the first pixel (I've verified with a multimeter I can read 5V all the way to the end), and then just solder directly to the second pixel's data in? Do I have to Remove the first pixel completely and resolder everything?
Thanks.
P.S. HOW I RULED OUT OTHER ISSUES:
- The code being supplied to the rainbow-y strip works on every other strip.
- I've swapped around power wiring, and tested it with a multimeter.
- I've swapped out the data pin with other strips and that works.
