I purchased a NodeMCU to control WB2812B light strips, following this guide, I made all the circuits:
https://github.com/bruhautomation/ESP-M ... gital-LEDs
I've never been able to get the lights to react, so I started to do some searching and testing.
So far I've reduced the strip to 10 LED's (originally about 460 and configured as such in the .ino for FASTLED), I've also noticed that in the original link the 5V LED strip was connected to 12V incorrectly (which I followed), that gave some side effects I wasn't able to explain (some leds were half powered on).
I've since corrected this by connecting the LED strip to the 5V power supply instead after seeing this project (which is a spin off of the Bruh one above but edited slightly for a few more features and integration into OpenHAB which I use): https://github.com/bkpsu/ESP-MQTT-JSON-Digital-LEDs
In his videos I noticed he actually powered the nodeMCU and LED strip off of a single 5V adapter which made me go ah-ha!
That said, no matter what I do I cannot get any response from the strip at all. The first LED lights up green when connected to the output pin on the MCU but that's it.
I've wasted a few hours attempting to troubleshoot various things. Even trying a Wemos D1 mini is Tasmota installed to attempt to drive the led strip for a reaction that doesn't rely on me using MQTT commands (https://github.com/arendst/Sonoff-Tasmo ... RGB-Shield), still nada. I've spent a few hours google searching about FASTLED options, and ESP8266 output mapping, etc. But I don't believe the program is at fault (but have attached a link to it as I have it right now for review): https://drive.google.com/open?id=1FONCG ... P3bKxvHAYH
I'm at a loss and not really sure where to look next any help would be appreciated.
