Hey all, I'm new here.. I'm trying to figure out what I can use an Infrared transmitter for. I have one built into my laptop (Dell D810). I've seen online that you can use it to transfer files onto a PDA or something.. But are there any programs I can get so I could control a TV or a stereo? I've googled so many combinations of words trying to find the answer but all I can find is ways to build IR sensors from scratch. Any help would be useful, thanks.
