I am new to individually addressable LEDs, but found the YouTube videos by DrZzs and The Hook Up. I have basically purchased hardware based on The Hook Up videos including a NodeMCU and several WS2812b strips.
I had prototyped my board and was just getting ready to flash his code when I recalled in his “what would I do different” video this year he strongly suggested WLED instead. I have an IT background and am familiar with coding so I was following his program but decided to switch to WLED because of the various options for access seem easier.
I have two questions:
- I was thrown a loop when, on the WLED getting started wiki page they showed a resistor and a capacitor between the logic level shifter and the first LED. I tried the flash without them and only get 1 LED to light up. I don’t have my logic level shifter installed yet so maybe the reason. That comes tomorrow. But what are the resistor and capacitor for? Are they required? I don’t see anything about those on The Hook Up.
- Does WLED support multiple channels DIO pins? Everything I could find on the wiki only talks about 1 pin (D4). If so which pins and how do I configure them?
