Hi,
Have you downloaded the zip and rename/copy the irremote folder to your library.
Once you done that, you can run the included ir receive dump or demo sketch.
If you connected the 3pin ir receiver correctly, you should see it display the codes in hex and raw data in the serial monitor when you press a button on your remote. you have to open the serial monitor under the arduino menu.
I'm not to far off from you. I'm not a software head either so struggling with this. At the mercy of these wonderful people here in this forum...
