SantaFeFan posted:I think that is one of my designs, been a long time though and I am not sure. As I recall I used an op-amp not a processor to regulate the element. Anyways I don’t think you can run a fan motor, just an element. I probably left the center pin unconnected as a spacer between the 2 smoke element leads to prevent potential. shorts.
That makes sense, I was amazed it needed a uP for a smoke unit. Don't think I've ever seen that board.
shawn posted:I know one output is for lighting . The other for smoke. I trying to figure out if the middle pin for smoke is present. Or, if I can run a fan drive smoke unit directly from it’s outputs....
It would be pretty easy to simply wire the smoke unit up on it's own. What specific smoke unit are you considering?
