Hi Kirk, For the single channel ADC do you have a chip picked out? I think that I'll just use the MAX186 in the article and ground the unused inputs unless you have a better one. A quick google search and it seems to be used a lot.
Nosing around on Maxium's site I found some chips that take 0-10v like this one http://www.maxim-ic.com/quick_view2.cfm/qv_pk/3998 Do you think it could be used? If you could hook an analog sensor to something like this then WOW! Distance sensing and more... Does a simple voltage divider circuit sound good enough to scale the voltage down to what the chip needs? I'm familiar with C, and just found the comp tool. I'll see what I can figure out... This is kinda new ground for me so any tips would help...
