IR Remote Hack using 89c52

[kisstronics]

Hi,

I would like to Switch On my Ac remotely. So I decide to make a IR transmitter, But the the circuit is able to first read the IR data and then play back it.

Is it possible with 89c52. Please help me...

What is Ac ? You mean on AC (Air Conditioner) ?

You can see attached projects. You can capture and repeat, also second project give you possibility to capture analyze and make your IR remote with that commands.

Yes,

But I have to complete it with 89051 Family only.

Right Now I able to send the IR data to Air Conditioner by Receive IR data by IR receiver and send it to PC serial port and by using Hyperterminal application I read the data and now I am trying to send the same data using MAX232 to 38khz frequency generator circuit(555).

IR Rx----->MAX232--->PC SERIAL PORT.

PC SERIAL PORT---->MAX232--->555(38khz Generator)

If I make a short circuit at max232 the received ir data will transfer to ac and is working fine and at that time I am able read the data using Hyperterminal.
But When I send the same data from PC it is not working.
