App to emit IR signal at desired frequency? topic

I'm sorry, this probably belongs in the "Apps" part of this forum.... but I was just wondering if anyone has heard of an app like this? I specifically want my OGP IR port to be able to emit a 56kHz signal. I am using an Arduino-powered infrared receiver for a project for my Engineering class and I wanted to test it, but I do not have access to a 56kHz IR beam anywhere besides in the Lab--to which I have limited access.

If I can't make the phone do the 56kHz signal is there any other at-home method for me to accomplish this?

Thanks!
