Can we do this? (aka The DIY Cruise Control Thread)

EDIT: I see you mentioned it can sense the difference between the switches, so I assume this drives both LED's. Again though, if you post the schematic I can etch actual circuit boards (instead of perfboard) for you or anyone else if there is interest.

It just drives the power LED. Because the switches are all paralleled together, the ADC is required to differentiate the on/off switch from the other three.

The problem with driving a SET LED, based on just the switch, is that there are too many conditions where you could press the switch, but not really be "set". Tonight I should have a chance to drop the schematic into ORCAD. If there was enough interest in the modules I figured I would do a run of boards.
