X10 Beginner

KE7GKP:
I don't understand what you are asking. You wanna try that again?

I was just trying to understand how X10 works by clarify the terminology. My question was:
The Arduino sends a signal to the X10 controller, which sends a signal to the inidividual light bulbs or to the switches?

Not sure I understand that question, either.

Ties in with my question above, I was trying to understand if I needed some specific X10 Compact Flourescent Lightbulb or if ANY CFL's work...
Same goes for the switches, do they need to be specific X10 compatible light switches? Or just ones that match the type ofr lightbulb (dimmable/non-dimmable)...

No. I mean a standalone X10 controller. Make sure you have X10 working before you introduce Arduino into the equation.

So the "X10 controller" we are talking about connects to the the "Interface module", which connects to the Arduino?

Any recomended X10 controllers?
