The fear of presenting paper is common amongst the students. It is surprising and saddening that students lack the grit in them to go ahead and present just the contents prepared by them toiling hard for months. It is easy to surpass any obstacle when you enjoy what you are doing and it is just what...

Android is an open-source software stack for mobile devices that includes an operating system, middleware and key applications. Google Inc. purchased the initial developer of the software, Android Inc., in 2005. Android’smobile operating system is based upon a modified version of the Linux...
Project Document on I2C MEDICAL DEVICE IMPLEMENTATION
ABSTRACT
I2C (I2C) is an acronym for Inter Integrated Circuit. The I2C bus is a bi-directional, two-wire serial bus that provides a communication link between IC’s. There are three data transfer speeds for the I2C bus: standard (100 Kbps), fast...
CONDUCTORS
These are materials in which it is easy to get electrons to move and provide a flow of electric current.
Conductors are mostly metals such as gold, silver, copper, iron and lead.
Carbon is a conductor as well as some gases (as in fluorescent tubes) and water containing some chemicals.
These...
The diagram below shows passive components, resistors, capacitors and inductors, and also electrical components such as switches, relays, motors and lamps. Also shown are the symbols for wires that are not joined ( no physical electrical connection ) and wires that are joined ( a physical electrical...
Amplifiers are used to increase the voltage or power amplitude of signals. They have many applications.
AUDIO VOLTAGE amplifiers boost the amplitude of signals between the frequency range 20 Hz to 20 KHz. This is the range of human hearing.
They are often used as PRE-AMPLIFIERS before the main amplifier.
AUDIO...
Security is a prime concern in our day-today life. Everyone wants to be as much secure as possible. An access control for doors forms a vital link in a security chain.
The microcontroller based Door locker is an access control system that allows only authorized persons to access a restricted area. The...
Industry is the one side of the Indian economy which has seen the maximum amount of mechanization, simultaneously creating a base for international trading ties at its very core. And the kind of technology today needs to be constantly maintained and upgraded not only due to wear and tear but also with...
The main objective of this system is to transmit message or text through ordinary Land Line Telephone from one end (source) to another end (designation). This is get achieved by the DTMF technology. It has two sections one for editing the text and to transmit the edited text and the other section consist...
This is a power generating method from sunlight.This method of power generation is simple and is taken from natural resource. This need only maximum sunlight to generate power. This project helps for power generation by setting the equipment to get maximum sunlight automatically. This system is tracking...
This Project is used to control a single phase Motor from any where in the world through the telephone. The circuit consists of a DTMF tone detector and a powerful 8 bit Microcontroller AT89S52. The Microcontroller senses the DTMF signal through the DTMF decoder IC MT8870 and it switch on/off and speed...
Do you know our 8051 microcontroller can play music tones, here’s an sample.
The circuit & code given here will play the music for “wishes you to be safe”
The IC LM386 is just an audio amplier, you can use any audio amplifier circuits.
More projects with music to be coming soon here
CIRCUIT...
In this Project it is proposed to design an embedded system which is used for tracking and positioning of any vehicle by using Global Positioning System (GPS) and Global system for mobile communication (GSM).
In this project AT89S52 microcontroller is used for interfacing to various hardware peripherals....
ECE MINI & MAJOR Project on Telephone controlled Remote switch (AT89S52)
This Project is used to control our household electrical devices from any where through the cell phone. The circuit consists of a DTMF tone detector and a powerful 8 bit Microcontroller AT89S52. The microcontroller controls...
