Multiple LEDs
Opened this issue · 0 comments
hello,
I am sure i am missing something pretty easy, What i am trying to do is have multiple lights controlled within the advancedDimmableLED.ino
For some reason I am unable to figure out how. Any pointers and help would be highly appreciated.
i pasted the code underneath. I am new to the whole esp8266 world.
