you're just about talking over my head a little. I think my sensor is on a "shield" already, I didn't buy the standalone sensor, I got the one on the little board, not sure it's technically shield.
I hope you mean by 6 channel that you are either monitoring and controlling six different parameters or even co2 sensors (that would be better so I could just trim down to a single channel easier). Right now all I have is the little arduino relay boards, may look into larger relays or contactors in time and all I need is binary, not pwn output yet, just on or off.
I don't have any plans that call for dimming or anything like a 358 yet, but that may change if I can really get this crap figured out. I've never been good at coding/programming even after college level classes.
going to check out your stuff now, thanks and I will try to spread the love a la the stinkmaster, as he commands it
