Data Communication Through visible Light
Li-Fi is a mobile wireless technology that uses light rather than radio frequencies to transmit data. In Our Final Year Project, we will be working on end to end platform of transceiver of li-fi . we will use Arduino UNO as microcontroller of sending and receiving the data from LDR (Light Dependent Resistor) .
Our system will be divided into two sub parts. 1This Data will be converted from string to binary form and LDR transmitter will transmit the data which will be received by 2Receiver and will again be converted from Binary to String.

We are going to show that how light can be used for data receiving and sending purposes.
The data will be sent with the speed of light but the processing (conversion from string to binary and from binary to string) of Arduino also matters.
Data will be sent by busing light. When we send data before sending the data will be recieved by the Arduino which will transform it into the binary form. When data is converted into binary and it will be send by the help of LDR tranamitter from 1 PC. On the other side the data is recieved by the LDR reciever it passes the data to Arduino which again convert the data back to original form and sdisplays on the screen. The data will travel with the speed of light.
1. The data will be sent by the help of light.
2. High transfer speed.
3. Far better than the speed of wifi.
4. Instead of radio spectrum uses visible light spectrum.
5. Data travels with the speed 100-200 GB/s.

The data will be sent with the help of light. The arduino convert data into binary form and LDR/LED will transmit the data and the LDR reciever recieve the data and Arduino will convert the data into the original form and displays on the PC.
