how does UART work??? (explained clearly)

UART is one of the many ways that computers communicate with each other. In this video I explain how UART transmission works. It all comes down to how voltages represent bits that make up binary data. In my demonstration I am using an Arduino board to generate The data signal and a RIGOL DS 1102E oscilloscope to visualize that signal. Comments, questions, and concerns are welcome. Thanks for watching!
