Serial
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.

Featured Examples
Send and Receive Serial Data Using Arduino Hardware
Use Simulink® Support Package for Arduino® Hardware to send and receive serial data with Arduino hardware.
Encode and Decode Serial Data Using Arduino Hardware
Use Simulink® Support Package for Arduino® Hardware to encode and decode serial data with Arduino hardware.
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.
Read Serial Data from GPS Shield Using Arduino Hardware
Use Simulink® Support Package for Arduino® Hardware to receive serial data from a GPS shield on the Arduino hardware.
Send and Receive Data of Variable Lengths Using Arduino Serial Communication Blocks
Use the Serial Transmit and Serial Receive blocks from the Simulink® Support Package for Arduino® Hardware to transmit and receive data of variable lengths on the Arduino serial port using a USB to serial converter.
