adds code


Modularity and hardware/software compatibility are among the most important features of an IoT device. In our latest video, we demonstrate just how straightforward it is to integrate an Arduino Uno relay shield with Siemens IOT2050 or IOT2040 devices for real-world interfacing. Additionally, we showcase the use of Node-Red for testing the integration and provide a step-by-step guide on controlling a fan through a graphical dashboard. By the way, if you're not familiar with the Siemens IOT2050 SBC, check out our other video on SBCs and IOT2050 for a helpful introduction. Happy building and exploring the world of cool IIoT projects!
