The microcontroller can also communicate with other chips using common protocols like ''Serial'' (also called UART), ''SPI'', or ''I2C'' (also called Wire). You can then make the Core more powerful by connecting it to special-purpose chips like motor drivers or shift registers. Sometimes we'll wrap up these chips on a ''Shield'', an accessory to the Core that makes it easy to extend the Core. | The microcontroller can also communicate with other chips using common protocols like ''Serial'' (also called UART), ''SPI'', or ''I2C'' (also called Wire).
