Data is sent in 8-bit bytes, most significant bit first, with each byte followed by an ACK/NACK bit.
The master pulls the SDA line low while SCL remains high.
The master sends the 7-bit unique address of the target slave, followed by a R/W bit (0 for write, 1 for read).
I2C communication is master-controlled. The master initiates, manages, and terminates communication, generating the clock signal.
The master releases the SDA line to high while SCL is high, signaling the end of transmission. Advantages and Limitations Understanding I2C
SDA and SCL are connected to a voltage source via pull-up resistors, allowing devices to pull the lines low without creating short circuits.
