Raspberry I2C Bus

The Grove - 16 x 2 LCD module we use is an electronic module that uses an I2C communication protocol to communicate with the motherboard. I2C is a simple two-way twowire synchronous serial bus developed by Philips. It only needs two wires to transmit information between devices connected to the bus. Communication over I2C takes place on two lines: a clock line (called SCL) and a data line (called SDA).

Therefore, when configuring pins for I2C access modules, we need to configure pins for both lines at the same time.
