Hello all,
any body know how to edit PinMode Function of arduino UNO !!!

Thanks In advance,

Why, whats wrong with "original" version?
Where to find a PinMode depends on the version of your IDE, and OS.

on a PC IDE 0.22

C:\Program Files (x86)\arduino-0022\hardware\arduino\cores\arduino\wiring_digital.c

IDE 1.0 almost similar path.
