I2c: Overview

The master sends the 7-bit unique address of the target slave, followed by a R/W bit (0 for write, 1 for read).

The master pulls the SDA line low while SCL remains high. I2C Overview

SDA and SCL are connected to a voltage source via pull-up resistors, allowing devices to pull the lines low without creating short circuits. The master sends the 7-bit unique address of

Uses a Serial Data Line ( SDA ) and a Serial Clock Line ( SCL ). I2C Overview

Each slave device has a unique 7-bit (or 10-bit) address, eliminating the need for complex Chip Select (CS) lines used in SPI.
