We are taking OpenPLC on ESP32 to the next level by building a custom C C++ function block that sends PLC live data to an I2C LCD. This ESP32 tutorial demonstrates how to integrate this block, including code snippets for initialization and data display, making it a great ESP32 project. Learn how to connect your ESP32 to an LCD via I2C to visualize data, expanding the possibilities for Arduino projects for beginners and beyond.
