Lifi Communication by Arduino UNO Download Project 2020
Lifi Communication
Origin of the proposal: In today’s world, devices that generate radio waves are all around us i.e, mobile phones, wireless internet connections, and microwave ovens. As the use of WiFi is increasing , internet users are also increasing.Thus, there is an increase of load on the radio spectrum i.e. increase in radio waves that leads to congestion. Radio waves are hazardous to the environment and cause health issues (headache, weakness, asthma, cancer), affecting the growth of plant. Hence a new technology LiFi (Light Fidelity) is evolved.

It is a bidirectional and wireless optical mode of communication. It uses visible light which reduces the load on the radio spectrum and increases the speed, efficiency, and bandwidth of the spectrum. Here, data is transmitted using light whose intensity varies faster than the human eye to capture.
In this Design, a LiFi Communication Educational Purpose is able to communicate between computer to Microcontroller within the spectrum of light. Like in the video life to microcontroller data communication, we are able to communicate between computer to computer and application to the application by using one computer only
Light Fidelity. So, in simple terms, we can say that this Li-Fi technology is nothing but light-based wi-fi technology. And as we know, this Wi-Fi is fully networked, bi-directional wireless communication technology. Where data is being transmitted using radio waves. While in the case of Li-Fi technology, the data is transmitted in the form of visible light using the LED light source. So, these household LED bulbs and LED lamps which are used as a light source can also be used to transmit the data. So, first of all, let's understand how this Li-Fi technology works. So, if you see any LED light source, if you provide the constant current to this LED bulb, it provides the constant illumination or constant brightness. So, as we change the current that is flowing through the LED bulb, the illumination or brightness of this bulb will change. So, this principle is used for transmitting the data wirelessly using this Li-Fi technology. So, if no current or minimum current is flowing through this LED bulb then, the brightness of this LED source will be minimum. And that will be treated as digital 0. So, digital 0 will be transmitted at the receiver side. Similarly, when the light bulb is ON, we can say that if the maximum amount of current is flowing through this LED bulb then the illumination or brightness of the LED bulb will be maximum. And that will be treated as digital 1. So, whenever the LED is ON, so digital 1 will be transmitted at the receiver side. So, in this way, by flickering the LED light source very rapidly we can transmit the data in the form of 1's and 0's to the receiver. And if this flickering is happening a million times per second then we can not see this flickering with our naked eyes. And we can treat this LED bulb source as a normal regular bulb source. when data is coming from the webserver or the internet first it will go to the MODEM, which provides the necessary modulation to the incoming data stream. Then this modulated data is fed to the LED driver, which changes the driving current for this LED bulb according to the incoming streaming data. At the receiver end, if you see, the optically received data is first converted into the electrical signal using the photoreceiver or photodiode. And after the signal conditioning, this data is being fed to the computer or laptop. So, to receive this incoming data, at the receiver side we require the Li-Fi dongle
