In recent years, there has been a lot of interest in the idea of using Li-Fi technology to power intelligent systems for making smart cities. This idea makes use of Li-Fi transmitters and receivers, LDR and ultrasonic sensors, an Arduino controller, a variety of relays, and motors to improve safety and transform the drive-through experience. The brake automation, intelligent payment choices, and adaptive lighting features included in the vehicle guarantee a comfortable and effective driving experience. Li-Fi technology is a great option for increasing road safety because it allows faster and more secure data transmission. Real-time data gathering and processing are made possible by integrating multiple sensors and components, which help the system adjust and react to changing driving conditions. The system also has an easy-to-use LCD for control and monitoring. With every aspect contemplated, this idea offers a viable way to apply Li-Fi technology to improve safety and change the drive-thru experience.
