Design and Implementation of Bi Directional Wireless Communication Based on Low Power LED to LED Link IJTSRD
In this work, a pair of LED to LED transceivers had been designed and implemented for bi directional communication between two PCs. Previous work in LED to LED communication relies on software to utilize LED as a light receiver. The problem of such method lies in the difficulty of synchronizing transmitter and receiver. In this […]
Visible Light Communication for Visually Impaired People using Sustainable LEDs IJTSRD
We developed navigation system prototype for the visually impaired using LED lights. Where LED lights emit visible light with location data and a smartphone or blind person’s stick with a visible light receiver receives the data. The controller with receiver calculates the optimal path to a designation and speaks to the visually impaired through a […]
