My fob only outputs a code on demand, that is after I push the button.

Any of the motion detection programs that use webcams would detect the change 
in display, but with a multiplexed  display, I'm not sure how well.

Interesting point.. mine only has the 6 digit (7-segment) display, but I'm sure it's multiplexed (digit/segment)..

But, the mux rate is fairly high, compared to the "transition time" for the segments. So maybe I can average over some (short) time...

What I want to do is see what the temperature dependence is. (prompted by leaving the fob in the sun, and having the code rejected, presumably because it was "slightly ahead")
