This note will include a short practical video explanation.WRITTEN NOTE
I2C communication mainly uses two signal lines: SDA for transferring data and SCL for carrying the clock signal. Multiple sensors and displays can share these same lines as long as their addresses do not conflict. In the video, show an OLED display or sensor connected to a development board, identify SDA and SCL, and explain that power and ground are still required in addition to the two communication wires.
