Download I2C Arduino Uno Pins Gif. As of arduino 1.0, the library inherits from the stream functions, making it consistent with other read/write libraries. It's important to note that the i2c protocol was designed to enable communication between components on a single circuit board.

Connecting multiple I2C device on Arduino Uno R3 -Use ... from duino4projects.com

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. So i do not understand which pins i can use. It's important to note that the i2c protocol was designed to enable communication between components on a single circuit board.

Along with atmega328p, it consists other components such as.

You can watch the following video or read the written tutorial below. Some arduino models use different pins for the i2c connections, if you are not using an uno then check which pins you need to use. As of arduino 1.0, the library inherits from the stream functions, making it consistent with other read/write libraries. Before going to start this tutorial you must know a brief about i2c communication.
