How to interface Arduino with RS232 communication protocol

📘 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 RS232 serial communication is a widely used protocol for transmitting data between devices. It allows devices to communicate over long distances using a simple interface. In this tutorial, we will explore how to use RS232 communication protocol with Arduino using MAX232 module. For demonstration purposes, we will create a project that will ON or OFF a LED connected to Arduino from a Computer (Arduino ide serial terminal) by sending ON or OFF command through RS232. ***Full article link: https://embeddedthere.com/how-to-interface-arduino-with-rs232-communication-protocol/
