Hi all, i have little problem with nodered, i think the problem is the configuration i am using.
i have a relay that activates with 0V, and even using a BC337 i can't get it energized.
it seems to go the loop regardless of the command I issue from Google Home.
This is my configuration images.
reading the docs, i read that the GPIOs only give 3.3V and was using a BC337 to ground everything.
Is there anyone who can help me?
also connecting a simple LED I have the same problem, it seems that the voltage does not come out from the GPIO pins
