Overview The Arduino language is based on C/C++ and supports standard functions as well as Arduino-specific ones. I/O Digital I/O pinMode(pin, mode) Configures the specified pin to behave either as an INPUT or an OUTPUT. It is possible to enable the internal pull-up resistors with the mode INPUT_PULLUP. Additionally, the INPUT mode explicitly disables the internal pull-up.
