Hi,
Welcome to the forum.
Please read the first post in any forum entitled how to use this forum.

Look at these links.
https://learn.sparkfun.com/tutorials/ir-communication
https://arduino-info.wikispaces.com/IR-RemoteControl
You will see you can configure the Arduino to read your IR remote so you can then make the Arduino into a remote.
