I am working on a project that uses a push button to cycle through different lighting sequences. My question is how can I take and select only the functions I want? I would like to then modify colors, timings, etc. I am sorry for the lack of knowledge, but any help would be very much appreciated.

I did this some days ago in a hurry for another project. The idea is to store all wanted FX-numbers in an array and increment the index of this array to the current mode and then update the WS2812FX. Switches are connected to PINs 2 to 5 and switch them to GND. All button-states are read to one byte. Therefore the bit-state is checked in the loop(). Not pretty but working.

There is also a button for speed, color (off color_wheel) and brightness-steps.

Let me know if this helps.

EDIT: Cannot upload that file. Will paste code in a second comment.
