What is I2C?

I2C, or Inter-Integrated Circuit, is a communication protocol that enables multiple devices, like sensors and displays, to communicate with computers such as a Raspberry Pi over just two wires.

This protocol is particularly useful for Raspberry Pi users. Instead of requiring a bunch of wires for each device, I2C allows multiple devices to share the same two lines. This means you can connect many sensors, displays, or other components to your Raspberry Pi using the I2C bus without a messy setup.
