i am new to Node Red and most of programming.
Searching Google and the forum didn't help me at all, almost because english is not my native language and i dont understand most of the subjects.
My very little understanding of programming is more like boolean algebra used in PLC controllers some time ago.
i dont understand how nodes interact with other nodes. On every "wiring point" i can combine as many nodes as i wish, but how do they interact?
i have two nodes that have numbers in form of "19.5" or "23".
if Number A is higher than B, i want to get a boolean TRUE.
if this TRUE is valid more than time X, then use GPIO Pin on the Raspberry.
hope you can give me some tipps.
