I2C is a two-wire serial bus. There is no need for chip select or arbitration logic, making it cheap and simple to implement in hardware. The two I2C signals are serial data (SDA) and serial clock (SCL) and are both bi-directional. These are open drain output hence one need to connect pull up register on the SDA and SCL line
