IR remote control

[clifweb]

I have 2 remote controls that do the same job up and down and stop. One of the remote is for my screen and the other one is for my projector to get down.
They always have to work together so when I press down I need to make both of them to get down and both automatically stop when they get to the pre set locations.. How could I do it?
Please include schematic and programs that maybe I need to use.

IR Remote controls work by sending different freqency pulses for each button. The device has a detector (Uses an IR Phototransistor to detect the IR) that does that assighned function for that specific freqency.

OK ,can you post your schematic so that everyone can help you
I used to design schematic about it .I used IC PT2248 and PT2249
that's very good.
besides,you can also use TV remote to control ,and MCU to decode
signal from TV remote

I was thinking using two IR transmiters to do it. but don't know what circuits and componentes I need to use.

This is nice free program and simple receiver ,you can use only 1 remote contr.for all.
