I bought an Addressable High-Density RGB 72-LED Strip, 5V, 0.5m (WS2812B) and did cut it to have two segments (25/47 leds). I used the cutting recommendations from the website and followed the dotted lines to make a good cut. The first segment, close to the input connector works fine but I can’t get the second one to light up. Using an Arduino, I tried addressing from 0 to 47 and from 25 to 72 but that doesn’t do it. I feel there is something missing in my setup, I`m using the wires at the second end of the strip to power/control it. Is there anything special to do at the cut end of the strip? any other ideas?
