The Department of Communications Engineering Technologies participated in presenting the “Li-Fi (Light Fidelity)” project during the Fourth Sustainability Week, held on 13/4 at the Energy Research Center at Al-Mustaqbal University, the leading private university in Iraq. The project was supervised by Dr. Noor Abdul Kareem Mohammed Ali and implemented by the student Montather Tawfiq. The project represents one of the modern technologies in the field of communications, as it relies on using light to transmit data instead of radio waves, providing a fast, secure, and environmentally friendly communication method. It also contributes to reducing electromagnetic interference, supporting the Sustainable Development Goals, particularly Goal 9 (Industry, Innovation, and Infrastructure) and Goal 7 (Affordable and Clean Energy). The project included the design and implementation of an integrated system using an Arduino Uno microcontroller. Digital data were converted into light signals via LED lamps at the transmitter side and received using an LDR sensor at the receiver side. The signals were then decoded and displayed on an I2C LCD screen. This project reflects the department’s direction toward adopting modern technological innovations and linking them with sustainability concepts, as well as enhancing students’ practical skills in smart communication fields, in line with the university’s efforts to support scientific research and encourage innovative technological solutions that serve society.
