Turning a smoke machine on/off with a triac

[ardhuru]

A triac would be fine. Even better, add a few lines to detect the zero crossing, and switch on right after that. That should reduce the inrush current.

Good idea. I have at least 1 pin spare on the PIC. I'll do the same for the pump too

Or drive the triac with an opto isolator that includes zero crossing detection.
