This is my first post here. I've been reading back posts and doing some searches and it's great to see so many who are willing to share their knowledge.
I want to be able to use my PC to log my furnace cycle and run time. I can provide either 24vac or 120vac signal, or if necessary drive a relay to provide a dry contact.
What is the easiest (cheapest) way to do this?? What software should I use?
I've read a few threads about the PIC but that seems overly complex for what should be a simple problem.
Any insight is appreciated.
