I have straggled with RGB lights and make some sequence with it. I am searching internet for some sequences with lights for 3 GPIO pins but I have found none. Do you have any idea how to combine those three nodes to make some sequences with RGB lights?
Do I need to use function node with some script? Is it possible to make some sequence without knowing the javascript, python code?
I want to make some smooth transition from one color to another in specific time

Are these RGB lights in addition to the relays?
Is it a single light controlled by the pi?
What type of light?
How are they connected?
What three nodes are you talking about?
[Update] as I see you have opened a new thread about the RBG lights I’ll close this thread. If you have more questions about the original issue,you can reopen the thread.
