Abstract:
The most common signage for people who are blind is restricted to tactile displays. This requires persons to be at the location of the signs before they can identify the information it bears. Using such signage as an aid in locating and traveling to a telephone booth, bus stop, elevator, public electronic terminal, building entrance or exit, leads to the paradoxical effect of having to already be there before one knows where it is. in addition to the problem of locating specific travel goals, very often blind travelers are una ....etc

Infrared Remote Control

The transmitter circuit includes IR LED, 2N2222 NPN Silicon Transistor , 2N2907 PNP Silicon Transistor.When the switch S1 presses LED emits IR light. The receiver part mainly consists of LM308 Op Amp IC , LM567 Tone Decoder, and NPN Phototransistor and a relay.

INTRODUCTION:-
A remote control is a component of an electronics device, most commonly a television set, used for operating the device wirelessly from a short line-of-sight distance.
The remote control can be contracted to remote or controller. It is known by many other names as well, such as converter clicker, didge, flipper, the tuner or the changer. Commonly, remote controls are Consumer IR devices used to issue commands from a distance to televisions or other consumer electronics such as stereo systems, DVD play ....etc

his Project ?Infrared Remote Switch? is used to Switch
On/Off an electrical appliances which may be Light, Fan etc
The Remote control used is an ordinary TV remote control
which should be pointed towards the Kit and by pressing
any button the device connected to the system will toggle
on every button press.
The above system is monitored and controlled by the 8 bit
Microprocessor. The Microprocessor continuously monitors
the Infrared sensor and if it sense infrared signal then it
latches the sensor and the microprocessor toggle the load ....etc

“Design and Development of 89C51 Microcontroller Based Infrared Remote Control system for Audio Amplifier”
Introduction
 It consist of two sections:the receiving section and the transmitting section.
 The receiving section consists of an Infrared remote.
 In this project I’m using a Sony Infrared remote.
 Whenever a key is pressed on the remote a coded pulse train is emitted. The pattern of the pulse train depends on the key pressed.
