There are usually two wires, one is for transferring data (SDA), the other is a clock which is used to mark the begin and end of data packed (SCL). As it is asynchronous it doesn’t need to send clock signal along with the data signals. It is our first kit with digital components, such as 7-segment displays, OLED display, D/A converter or I2C Bricks, complementary to all analog bricks.
