I am having some trouble compiling this library for ESP8266 Wemos D1 mini. I have installed the library though the Arduino Library Manager (v1.0.0). I have also tried downloading the zip from github and same thing. I am using Arduino version 1.8.19 under linux. Just with the include -no need to instantiate any object- I start getting quite a few compile errors.

Error compiling for board LOLIN(WEMOS) D1 R2 & mini.

I appreciate if someone can help on this.

Hi!

Like the title says, could a breath effect be implemented in the library? (A fade in + fade out forever effect)?

Also, to add any type of blink array pattern? Something like this: pattern[] = { 100, 500, 100, 2000 }; -- So on for 100 ms, off for 500ms, on for more 100 ms and off for 2000 ms?

And one more thing.. if possible.. ... maybe a two color led setup, like create yellow from red and green common cathode leds.

Just some ideas. I'm using a Single Led Library that has pattern and breathe effect. I had to manually create the "yellow" led also, as the Single Led Library also doesn't have it.

Thanks!!
