It consists of 2 pins only (one for serial data and one for the serial clock). I 2C, I2C, or IIC ( Inter- Integrated Circuit) is a very popular serial communication protocol that’s widely used by different sensors and modules in embedded systems. Arduino I2C Example – I2C LCD 16×2 Interfacing.I2C Communication Between Two Arduino Boards.Arduino I2C Communication Configurations.Without further ado, let’s get right into it! Table of Contents In the second project, we’ll do an I2C Communication Between Two Arduino Boards. We’ll create a couple of Arduino I2C projects in this tutorial, the first of which will be Arduino with I2C LCD 16×2 interfacing.

In this tutorial, we’ll discuss Arduino I2C Communication from the very basic concepts all the way to implementing Arduino I2C-based serial communication.
