47+ Arduino Nano I2C Example Background. In this tutorial we will learn how the i2c communication protocol works and also we will make a practical example of it with the arduino board and a sensor which uses this protocol. We have to define the hex address of our display and what display we are using like 16×2 or 20×4.

I got some arduino nanos at really good price on amazon and wanted to connect a 7 segment led display with an i2c backpack. You probably think (as i did and as the guys laying out the pinout once you wire it up correctly, this arduino i2c scanner will let you know you have proper connectivity and the address for the device In your arduino ide, check your examples menu and locate the 128×64.

I2c lcd 1602 display x 1.

Maybe it is because many of the pinout diagrams for the nano have scl and sda on the wrong pins. External power supply (regulated 5v). In this tutorial we will learn how the i2c communication protocol works and also we will make a practical example of it with the arduino board and a sensor which uses this protocol. I use the 20×4 display in this example.
