Infrared-Led based Wireless Data & Voice Communication with Circuit Diagram

For years, infrared LED has been merely a system for piping light around corners and into the inaccessible places to allow the hidden to be lighted. But now, infrared LED has evolved into a system of significantly greater importance and use. Throughout the world, it is now being used to transmit voice, television and data signals as light waves. Its advantages as compared with conventional coaxial cable or twisted wire pairs are manifold. As a result, millions of dollars are being spent to put these light wave communication systems into operation.

Model-Based Approach to Demodulation of Co-Channel MSK Signals

Abstract :-
Co-channel interference limits the capacity of cellular systems, reduces the throughput of wireless local area networks, and is the major hurdle in deployment of high altitude communication platforms. It is also a problem for systems operating in unlicensed bands such as the 2.4 GHz ISM band and for narrow band systems that have been overlaid with spread spectrum systems.

Project on Electronic Dhol

Abstract :-
The drum utilizes several peripheral amplifiers and Analog-to-Digital Converters (ADCs) plus an Atmel AtMega644 to produce the different sounds. A drum hit is recorded when one of three independent force transducers are triggered by vibration, depending on which one was triggered, the corresponding sound is played. Traditional dhol was modified to electronically produce three different sounds, as well as be able to record a drum sequence and have it play back, for learning purposes.

Exercise Monitoring System

Abstract:
Our project inspiration came from a previous project both of us had worked on a previous year. At that time, we had both worked on separate projects involving a simple Pedometer using a MSP430 microcontroller. Unfortunately, due to time constraints and hardware failures, we were unable to complete the project. Unwilling to accept defeat, we attempted the project again, but with the intention of providing greater functionality, better user interface, and a working final product. While we understood that many smartphone apps provide a similar functionality, we wanted to see if we could provide comparable functionality without all the need for fancy hardware and expensive data plan.

Automatic Rain Sensing Wiper Cum Headlight Controller

The world today is moving ahead at a very fast pace. Some of the very common examples of fast moving objects are aeroplanes, high speed cars and many more. In our everyday life we come across many fast moving vehicles and so it is very important to measure the speed of these vehicles.

Pre Paid Energy Meter With Microcontroller Programming

Abstract :-
In this project we show that how we interface the digital energy meter to the easy recharge unit and convert this meter into prepaid energy meter. By using this technique we show that how we convert all meter with the prepaid logic. When any concept is prepaid then there is a security of misuse of electricity uses. Normally in every postpaid connection bill is much higher then the prepaid. Continue reading Pre Paid Energy Meter With Microcontroller Programming
