$100 for an oscilloscope? Go to your local electronics store and pick up a three pin IR Receiver that takes up a single Arduino pin, for $4.50.

Not only is it cheaper, it’s way easier to read from and with a library like this:

You’ll be acting on specific buttons with a single line of code.

I’m new to this as well; check out my mini collection at http://www.vulcan.it.cx/arduino – There might be something useful there

You can get an Arduino for about $20-$30. I don’t know how much the photodiode and infrared LED were. I expect you could get them for under $1. The oscilloscope I used is about $100 I think, but there were 2 comments at the top from Steve and Josh about cheap ways to build an oscilloscope.

To decode what the remote was sending, I used an oscilloscope and a small photodiode. The photodiode generates a small amount of voltage when light hits it, and responds to changes in light level quickly enough that the oscilloscope can draw a really nice plot of the signal. I have a Parallax USB oscilloscope, which is perfect for showing the command pulses and is just fast enough to find the modulation frequency. As an aside, I’m really happy with the Parallax oscilloscope for projects like this. It is simple to use and I love being able to save images to share with people.
Here’s what two of the commands from the dimmer remote look like. The top signal is the “fade lights up” command, and the bottom one is “fade lights down”:

Thanks alot for this tutorial. I used this info to make a homemade Slingbox and it works beautifully!!!
