I've a Elmo Pan/Tilt camera in one room and need to control it with the infrared remote from another room, if I put a infrared receiver in in front of the remote and feed the signal into a Arduino then I can re-transmit the command (through a wire) to an infrared LED in front of the camera, my question is how do I decode the command and re-transmit it.

Cheers!

 

If it's just a pass through, you don't need to decode it...

However, since you are trying to control it from another room, IR doesn't seem like a good option...

 

There are numerous arduino tutorials and libraries for decoding/sending IR

here are just a few from "google"

Thanks for the link, it's exactly what I'm looking for.

 

Good lord, people actually use a micro for this?

Take a plain 38KHz IR receiver and use it's output to gate on and off a '555. Set the 555's RC for a to nearly square wave at 38KHz. Drive an IR LED with that.

And just make sure the receiver can't see the emitter.

 

yes a 555 IR repeater is simple too..
