I have installed the BTF-LIGHTING WS2812B RGB 5050SMD strips in my rec room along the ceiling. Problem is that I have an opening on the one side where the stairs are. There is noway for me to continue the strips on the other side of the opening. Can I add another strip where I started in the first place and go the opposite way? Also using the KeeYees Development Board WiFi WLAN Wireless Module for ESP8266 NodeMCU ESP-12E CP2102.
Sure. If you just connect each data wire together, they will be mirrored. You can also connect it to a second pin.
