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 work, a fully hardware based solution is implemented using low current Op Amp. The proposed method yields higher baud rate and requires no software overhead microcontroller less . It is also concluded that the maximum communicable distance of the link is inversely proportional with the baud rate.
