This is code for mixing timing change and button press. Change the time or add a physical 2 state switch for checking on-off.

Sorry, I don't know how to use git.

Hello There

Good day

I have compiled a collection of FastLED simulations (all based on your examples provided)
I would like to request you to add the wokwi simulator link to your readme page if you find this simulator helpful for your viewers.

if you have any suggestions or feedback, please feel free to suggest.

Thanks in Advance!
