Communication using serial port interface

Serial communication is the most common low-level protocol for communicating between two or more devices. You can effectively use serial communication via Universal Asynchronous Receiver-Transmitter (UART) to exchange, control, and automate across applications using your Arduino^® board and host computer.

Send and Receive Data Between Arduino and Host Using Serial Communication

Use the Serial Transmit and Serial Receive blocks from the Simulink® Support Package for Arduino® Hardware to transmit and receive data between your host computer and Arduino hardware using a USB to serial converter. When the Arduino hardware receives data, it transmits back the same data to the host. The host then displays both the transmitted and received data on the scope.
