Then your input pins are floating and won't give a reliable signal. Use INPUT_PULLUP. When the switches are closed, the pins will read LOW, not HIGH as your code currently expects.


No luck. Errors out when I Try to compile.

That's an unrelated error. Undo your changes or go back to the code in post #6 and see if the error goes away.

Did the IDE auto-upgrade itself or some libraries? There was a recent post about this error on the forum.


Try this:
This is a bug with the version of the compiler used in the most recent AVR board package releases - it happens to some people, but not most (don't get me started about what it says about Arduino that they have not addressed this by either downgrading or upgrading the compiler version in the released core) .

Tools -> Boards -> Board Manger, for the official AVR board package, select 1.6.21 (that's the latest good version), install it, and restart the IDE.


I just swapped out the board to build for and was able to upload. But still nothing. Have experiemented with while loops but that isn't working for me either.
