A 2X4 samples every 10 milli seconds if debounce is disabled. This means that if a signal is less than or equal to 19 milli seconds, there is a good chance it will be missed.

My recommendation is to use the 5VDC from the 2X4, and rig up a latch, with one of the outputs from the 2X4 used to reset the latch. You would sense on the input the signal, and then create a link to the output to reset on sampling a signal (plus a broadcast to whatever device you want). This should only be a couple bucks from Digikey, however it will involve some soldering skills…

Let me know if you want more details on how to rig something like this up.
