HELLO SIR,
I'M A STUDENT OF B.TECH , FINAL YEAR. I WANT TO WORK ON 12 CHANNEL INFRARED REMOTE CONTROLLED SYSTEM. FOR THIS I'M USING AT89C2051 MICROCONTROLLER. SO, PLEASE PROVIDE THE REQUIRED PROGRAM SO THAT I COULD GIVE A PRESENTATION ON IT .PLAESE HELP AS SOON AS POSSIBLE.
I SHALL BE OBILIGED IF U DO SO.
THANK YOU. ....etc

Dear sir, I am doing a project on the infrared remote control circuit design using the IC CD4027 and IC 555 and also a photo modular TSOP 1738 for switching on and also off the household appliances like lights,fans, etc. I need a completed project report for the same with the circuit diagram, whixh i have to submit in my college lab. Please help me as soon as possible as i need it immidiately. Thanking you. ....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

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.

Construct a high-gain portable audio amplifier that is sensitive to a fluctuating infrared
light using the recommended circuit and equivalent components listed. Soldering,
drilling, and gluing will be required. The MC1458 dual op amp specification sheet is
available online. Each person will prepare an individual semi-formal lab report. Your
grade is based on the working project (40%) and your individually written report (60%).
Each group will work on building the tester, but reports are to be done individually.
There will be no credit for ....etc
