How to Send Data Between Arduino Using RS485
In this tutorial, we'll demonstrate how to send data between two Arduino Mega boards using TTL to RS485 modules for reliable serial communication.
We’ll walk you through the wiring connections, show you the exact diagram needed, and guide you to download the Arduino code from drive.google.com/file/d/1T5s4XEu1BGQrcTuibkvQHxGcr93faPkf/view and upload the necessary Arduino code.
One Arduino will be set up to transmit data, while the other will receive it.
Once the code is uploaded, you’ll be able to view the transmitted data on the serial monitor in real time.
This guide is perfect for anyone looking to understand RS485 communication with Arduino.
