Data Communication through Li-Fi

In this Project. We used VISIBLE LIGHT (through LED) as the medium of transmission.By using switching property of LED approx. 10^9 times in a second.A very Fast Data transmission is made possible between two laptops,&between mobile, and Audio device.This project is chosen by us to provide very fast data transmission by using 10^5 times bigger spectrum of Visible light then that of RF and which is freely available and to use light as a medium of transmission where RF usually create interference with a working system, Hospital, AirPlane etc.

IR based Home Automation using Arduino

In this project, We provided a solution for switching of Household Appliances through our IR remote (TV Remotes etc).We used Arduino with setting IR sensor in it and programmed Arduino to sense and give corresponding output toward IR ray received from IR remote then Output of Arduino after amplifying with Amplifying IC like ULN2003 is given to Relays which are working as switch to Household Appliances simulate with IR input by remote corresponding switch on & off is performed .

Digital Object Counter

In this project, We developed a circuit which is capable of counting 0-9 units. Which is very helpfull in making a lot of 10 objects useful in packaging & Manufacturing industries. In this project we used LDR as the Passing by object sensor to the counter, IC 7490 as a counter , a 7 segment BCD display, IC 7447 as decoder IC for counter input from IC 7490 to BCD display ,with 2 555 timer ICs in monostable & Astable pulse provider to our counter and decoder ic. As object pass by LDR, we get an increment in our BCD display.
