Hi Angelo,
I am not sure what exactly you want to achieve with your project, so ist is a bit hard for me to analyze it properly.
Why do you multiply the variable "Tempo" by 1 and write it into "Moltiplicatore"? All it does is: Tempo = Moltiplicatore.
And, are you aware of the fact that Moltiplicatore always eqals 1 when the True-script is running and always 0 when the False-script is running?
What the Script Output Node does at the moment is:
If TRUE -> Send Art-Net 255 -> Wait for 1s -> Send Art-Net 0 -> Set Motor1 = Altezza_Voluta (and thus triggering the False-script)
If FALSE -> Send Art-Net 255 -> Wait for 0s -> Send Art-Net 0 -> Set Motor1 = Altezza_Voluta (which is already the case)
The Wait-command at the False-Script is more or less useless, I guess this was not the intention? Because I'm not sure if the Art-NetSetVal8bit,1,1,1 ,Value 0 command will be sent correctly so shortly after the first one.
Maybe I can help you better if you explain your approach a bit
Cheers,
Janina
