![]() The example shown here uses the Arduino serial monitor to allow you to type in data to send to the Master Arduino. ![]() This allows use of almost any Arduino pins for Serial Data connections, and allows simultaneous use of the standard Arduino USB Serial communications. The example Software Sketches below use the Software Serial library that is provided with the Arduino IDE. See details of RS-485 communications with Half and Full Duplex, network configuration and more HERE: Example Software Sketches ![]() This means it can send or receive on the same wires, but in only one direction at a time. RS485 as we show it in this example is Half-Duplex.
