I developed a smart user interface using a DWIN HMI display integrated with a microcontroller (ESP32/Arduino). The system provides a graphical interface to monitor and control different parameters in real time. The DWIN display communicates via serial (UART) and is programmed to show data like sensor values, system status, and control buttons. This project is useful for industrial control panels, automation systems, and smart devices.
