HI. i would like to know if i can declare 2 integer on 1 pin
if i do that can i use (digitalread,digitalWrite) any of them without problem?
You can declare both values to be 35, no problem. But if you're passing these to an Arduino function that expects to receive a pin number, such as pinMode(), then both values reference the SAME pin. From your later posts, I don't think the two values do actually represent input/output pin numbers as your example above implies so perhaps this isn't an issue. But taking the code above at face value, you are using two names to refer to the same pin and this is almost certainly not what you're trying to achieve.
