Writing my own programs?

Questions
1

So I got WLED running on a 60 lights LED strip. I would like to do some shenanigans triggered by a button. Is it possible to write my own scripts/programs to run on the ESP8266 which could a) detect buttons and b) control the LEDs?

Thanks!

Right - usermods. facepalms

I’m gonna read up on them, then come back with questions.

You may be good just using existing button logic with presets and playlists.

That worked perfectly. Thank you!
