 ## Introduction
 A good way of adding complexity of features to your projects without adding complexity of wiring, is to make use of the Inter-integrated circuit (I2C) protocol. The I2C protocol is supported on all Arduino boards. It allows you to connect several peripheral devices, such as sensors, displays, motor drivers, and so on, with only a few wires. Giving you lots of flexibility and speeding up your prototyping, without an abundancy of wires. Keep reading to learn about how it works, how it is implemented into different standards, as well as how to use the [Wire Library](#wire-library) to build your own I2C devices.

 ## What Is I2C?
 The I2C protocol involves using two lines to send and receive data: a serial clock pin **(SCL)** that the Arduino Controller board pulses at a regular interval, and a serial data pin **(SDA)** over which data is sent between the two devices.

 ## Serial Class
 
 With the [Serial](https://www.arduino.cc/reference/en/language/functions/communication/serial/) class, you can send / receive data to and from your computer over USB, or to a device connected via the Arduino's RX/TX pins.
