 To get the sketch working you'll first need to convert the inverted SBUS signal to an non-inveted signal as the arduino doesn't (at the time of writing this code) have the ability to invert it via code.

-For testing purposes you can just use a FTDI converter. However, you'll first need to configured the FTDI to invert the invertd signal back to a non-invered signal (confused? don't worry! just hang on here for a while). For a permanent solution, there are soem dedicated "inverter chips" that do that for you or just use a couple of  transistors and resistors, or you can do a simple hack on your receiver to tap directly into the non-inverted SBUS signal that's already on the reciever itself (duh- why don't the manufacturers just prodvide this as an output option?). See the video and webpages below, which explain all these methods to invert the SBUS signal.
