Yes IC. I have come to think of we who use Arduino as victims beneficiaries of the preprocessor, that init() off somewhere, and gee, you could be some time before concluding that there has to be a main() involved at all.
Given the number of times it's a missing pull-up resistor or failure to enable internal pull-up that causes some noob a headache, I would not have been surprised to find that the Arduino ppl hadn't just included switching them all on in the init().
THX again. All.
I'll try the several ideas I now have for my DIP switches and when none of them works ask y'all about it…
