Sure. You could program it so that until sensor #1 has been triggered,
sensor
#2 won't be activated. Once sensor #1 & 2 have been activated another
function could be activated. That function could activate a servo which
could
pull a bolt back, allowing a door to be opened.

Interesting idea, using the controller for a puzzle. Thanks.
