I have this cheapo RF remote/receiver that I got off eBay. Upon testing (just wiring it in-line with some LED strips), it works as advertised and even has some cool fade effects. For my project, I need to use a different transmitter, so I need to decode this set-up. I've Googled around and everything I've come across has been for RF receivers with three pins (data, vin, gnd) to catch the remote's signal. As this only has two, I'm not sure how to continue. How do I go about decoding it with my Uno?
The "block with wires" is most likely a receiver AND a LED driver.
Supply in, and LED out.
RF link could be 315Mhz or 433Mhz, maybe written on the remote.
Use another receiver with the same frequency, and connect it to the Arduino.
Example codes of receiver libraries show you the remote control code on the serial monitor.
RCSwitch has a sketch that does that.
When you know the codes of all the buttons, you can use a transmitter with the library.
Transmitters/receivers are usually sold as a kit.

It's 433.92Mhz. I do not have another receiver, I just have this. Will decoding it not be possible?
I don't know what's inside....
Better order a transmitter/receiver kit.
They are only a few dollars.
I guess you want to make a transmitter with your Arduino, so you will need to order a set anyway.

Does the attached image help at all?
And yeah, I just bought a separate transmitter with no receiver. So if I get a receiver, I'll be able to decode the remote's signal, correct? Would I still be able to use these LED controller receivers in the project? Just program the transmitter to transmit the same codes?
You might have to use several receiver libraries to find and re-transmit the right code.
RCSwitch has worked for the receivers I have tried.
You could post the IC numbers. Maybe someone can tell you something about the codes.

Alright, I'll have to wait a few weeks (vacation), but I'll see what I can come up with in the meantime. The part is shipping from China anyway, so it'll be a while. Thanks for your help.

Well I'm back now and have given that a go. I've hooked up the receiver to the Arduino and used RCSwitch's example to try to read the codes off the remote. I load up the serial monitor, hit a button on the remote, and... nothing. RCSwitch's site and the code itself seem straightforward enough. The remote has been tested and it works. Bad RF receiver or am I missing something?

That was part of your post that I quoted. Is my reply not showing up?
Okay, it CAN read signals after all. However I have to hold the remote only a few millimeters away from the receiver. I'll have to look into adding a longer antenna.
Also, yeah, I'll need to find some way to read the codes that I pulled.
