For effective data transmission with the Inter-Integrated Circuit (I2C) protocol using Arduino, it's often necessary to use external pull-up resistors on the designated I2C pins. Most Arduino boards don't have pre-installed pull-up resistors on these pins, but instead they offer exposed pads for surface mount resistors ("SMD"). This gives more flexibity on how these pins can be used. More specifically:

* The I2C designated pins can also be used as General Purpose Input/Output (GPIO) pins or for Analog-to-Digital Conversion (ADC). In this modes, pull-up resistors are not typically required.

* Users are not bound to use I2C with pre-set pull-up values. This is important because the optimal pull-up value can vary depending on different factors.
