I2C

Overview

I2C (Inter-Integrated Circuits) is a two-wire serial communication protocol that uses two pins for communication: a serial clock (SCL) pin and a serial data (SDA) pin.

Serial Clock (SCL)

• Purpose: Used for sending clock data between devices and synchronization.
• Control: Provided by the master device.

Serial Data (SDA)

• Purpose: Used for sending and receiving data between devices.
• Operation: Operated by both slave and master devices.
• Alias: Also known as the data line, while SCL is known as the clock line.
