WS2812b strip stopped working,what could be the possible cause? Answered
Hi, I'm using a 1m ws2812b (30 led/m) strip for my ambilight setup with adrilight, using an arduino mega. I cut the 1m strip into 5 smaller strips ['data direction as per this description': (5+5 leds in bottom) -> 5 leds at the left side -> 10 leds at the top -> 5 leds at the right side) ] and soldered them together, rechecked everything and installed it on my monitor. I'm powering it with a 5v 2a power supply and everything was working good for 3 days. Suddenly, the strip stopped responding to any data input from the arduino. Only the 6th led of the 2nd strip at the bottom lights up with 'green' colour as soon as I turn on the power adapter.
I tried using Adafruit neopixel rgb strand test as well as fastled library's sample codes but none work any longer(they were working perfectly prior to this sudden failure). It's as if the strip doesn't care that the arduino is connected. The single led (6th one as per data line & 1st one as per divided section, on the 2nd strip) works when connected to the power adapter and lights on/off as per the power adapter's state. None of the other leds work or even light up. What could be the possible problems of the sudden strip failure? Any help would be highly appreciated.
