Abstract: With the rapid advancement of smart technologies, the integration of smartphone-controlled devices has become an essential aspect of modern digital communication. This paper presents the development and implementation of a smartphone-controlled LED display capable of displaying scrolling text. The system utilizes a microcontroller-based architecture, such as ESP32 or Arduino, in conjunction with an LED matrix panel to showcase dynamic text messages. Communication between the smartphone and the display is achieved through wireless protocols like Bluetooth or Wi-Fi, enabling real-time message updates. The proposed system offers a cost-effective and user-friendly solution for applications such as digital signage, advertising, and real-time information broadcasting. The paper also discusses the hardware design, software implementation, and potential improvements for future advancements. Key words: Smart technologies, Smartphone-controlled devices, Digital communication.
