If we are going to be able to help you we need to know what you are working with. Do you have a data sheet for the IR receiver/decoder? How is it wired to the Arduino (a schematic)? Which Arduino? Which IR library are you using? Please post the code that you tried.

Please read the "how to use the forum-please read" stickies to see how to format and post code. And some hints on what we need to know in order to help you.
