This thing was extremely easy to hook up. All you need to do is supply a resistor (I used 200 Ohms, with a 3.3V supply) to the power line, GND it, then connect the data line to one of your digital pins (I used pin #2). The module itself contains the demodulation circuit so what you see is a solid signal. At this point, I decided to hook up my oscilloscope to see what was coming out of this thing. I programmed a free channel on my universal remote for a Sony DVD and started hitting some buttons
