The Wire library allows the Arduino to communicate with I2C devices using a simple set of functions. In the Arduino environment, I2C is implemented using the Wire library.
I2C is a popular choice for communication between devices because it requires only a few wires and can support multiple devices on the same bus. It is a two-wire serial communication protocol that uses one wire for data transmission and another wire for clock synchronization. I2C (Inter-Integrated Circuit) is a communication protocol used by microcontrollers to communicate with other devices, such as sensors, memory chips, and other microcontrollers. I2C communication is a serial communication method developed by Philips for the purpose of communicating between ICs. However, please note that in that case it cannot be used as an analog input. Analog inputs A4 and A5 is also available for I2C Communication in Arduino. It is written as I2C (SCL) and I2C (SDA). The I2C pins are on the upper right of the Arduino uno as you can see in the below figure.
The external view of Arduino UNO R3 is shown below. I would appreciate your support in this way! I may make a commission if you buy the components through these links. So in this article, we learn about I2C communication in Arduino. Example: How to Print a message on i2c LCD using i2c Communication in Arduino:.Wire library for I2C communication in Arduino:.
