Data transmission prototypes through wireless optical communication link using Arduino microcontroller
In this paper, Free Space Optical communication link prototypes have been practically experimented. Audio and text data transmission models are implemented using a programmed microcontroller “Arduino Uno”. Using a 650 nm laser source, a digital audio signal is transmitted with a data rate of 506.3 kbps in addition to a text data transmitted with a bit rate of 125 kbps. Both signals are received using a TSL250R photodiode. These prototypes create an FSO communication link designed for audio and text transmission. The use of Arduino microcontroller offers a more accurate transmission of higher quality. The concept discussed can be generalized for real optical communication systems instead of lab work only.
