Running I2C on Pro Micro (2) - Connecting with I2C

It seems that I2C is often used to connect multiple ICs and perform processing in custom keyboards and sensor modules. In this series, we will use the I2C port on the Pro Micro to operate an IO expander. In this second article of the series, we will look at the basics of I2C and its use on the Pro Micro.

Running I2C on Pro Micro (1) - Pro Micro Setup

In custom keyboards and sensor modules, it is common to connect multiple ICs using **I2C** for processing. In this series, we will use the I2C port on the Pro Micro to operate an IO expander. In this first article, we will set up the Pro Micro on a breadboard. Although I2C is not involved yet, this is an important step for the future. Note that this is an experiment, so we will implement it on a breadboard.
