As of arduino 1.0.1, it is possible to enable the internal pullup resistors with the mode input_pullup. How to use arduino board. Board digital pins usable for interrupts; Asked aug 21 '15 at 11:35. Configures the specified pin to behave either as an input or an output. For pin description of arduino uno, let us assume some basic numbering. After soldering connect the i2c module to arduino uno. These pins can be configured to work as input digital pins to read logic values (0 or 1) or as digital output pins to drive different modules like leds, relays, etc. This ground is intended for use with the i2c serial port that it is next to along with the digital i/o pins on that side of the board, and should only be used for lighter.
