Ok here it goes...
I have a projector remote that is dying, and i cannot buy a replacement. Is there a way to build a arduino circuit to capture, store the existing codes from the dying remote. Then replay them?

Help?

Yes that is possible. However it would be a whole lot easier if you could find out what codes the remote uses so you don't have to have the code learning/recording process to deal with. There are lots of remote IR codes published on the web, perhaps if you stated the manufature and model number of the projector someone might have a link to a database of remote IR commands for it.

ok, it's a benq pb6100. I have contacted benq and they can't even provide me with the codes, because this projector is 10 years old.

Our sample Gadget Shield sample application for IR decoding/transmitting (Universal Remote Control) should work with just about any protocol:

You don't need to buy a Gadget Shield, just use the code with your own hardware.

Power, ground, and signal. I have several and they work extremely well. It outputs pulses of 500 microseconds to 40 milliseconds, depending on your remote.

A simple IR led will work to transmit.

Somebody turned me on to the work Ken Shirriff's done with things IR and remote, if you're still interested --
