Question

Nested loop im Arduino is​

Answer 1

Answer:

☑️You've commented out a couple of the statements (while() and lcd.clear()), so it's rather difficult to expand the brackets to a readable state.

☑️But from what I can see, there's nothing inside the while() loops to change the "ButtonState" variables (unless you're doing that from an interrupt). So the if() statements never change their results.

☑️If you do change those variable in an interrupt, make sure the variables are global. But basically there's not enough info here to offer anything but a guess...

☑️Those while() loops are all infinite, BTW

Answer 2
