I have a project which will use 3x 2.5m WS2812B LED strips. I've noticed dimming at the ends, so I will need additional power somewhere else along the strip. I am planning on simply powering from both ends. My question is, do I only need to attach a single 5V wire on the end of each strip, without ground? Or is another ground wire necessary as well?
