Hello Please, Sorry to bother I'm a beginners..
Someone could help me in order to understand where I'm wrong..
I created a public project named PROVA 1 inside there are two schematic
1) PR LED and 2) PR TL082
About PR LED the question is why the simulator show the voltage of anode Led = power supply ?.. it seem that no ground connection..
About PR TL082 : why the pin output of TL082 is always 0 V?
