In this Arduino I2C tutorial we will use I2C communication between two arduino boards and send (0 to 127) values to each other by using potentiometer. Values will be displayed on the 16×2 LCD connected to each of the Arduino. Here one Arduino will act as Master and another one will act as Slave. So let’s start with the introduction about I2C communication.
