Arduino RS485 Modbus communication by using two Arduino boards

📘 If you want to understand how real embedded systems are designed beyond tutorials, I’ve put together a short practical guide based on my 7+ years of real project experience. 👉 50% launch offer available for the first 100 copies: https://hasaneee.gumroad.com/l/embedded-system-product-from-zero In this tutorial, we will explain how to communicate between two Arduino boards with the help of the Modbus serial communication protocol. Because Arduino doesn’t have any peripherals for Modbus communication. We will use an RS485-based module called MAX485 for communication between two Arduino boards. We will follow the RS-485 master-slave communication method. Full blog post Link: https://embeddedthere.com/how-to-interface-arduino-with-rs485-modbus-protocol-using-max485-module/
