-#### Introduction
 Inter-Integrated Circuit, or **I2C**, is one of the most widely used serial communication protocols, especially in the Arduino ecosystem. It enables multiple devices to communicate over just two wires, making it both efficient and versatile as you can easily add new modules more easily as the connections all happen across the same bus and standetizes them across manufacturers (and product lines).

 I2C communication relies on two wires:
 - **SDA (Serial Data):** Transfers data between devices.
 - **SCL (Serial Clock):** Synchronizes data transmission.

 1. **Two-Wire Simplicity:** Reduces hardware complexity.
 2. **Address-Based Communication:** Each device has a unique address.
 3. **Bidirectional Communication:** Enables data transfer in both directions.
