i’d like to react on the movement of people. when somebody goes through the door a soundsample should be played. so i’m wondering what’s the best and fastes way to do that?
i thought about using a photoelectric barrier, but i don’t know too much about electronics. i found one here:
but it is more expensive than i thought and i was wondering if anybody ever tried to connect a photoelectric barrier with vvvv and has some tips for me?
i really don’t know what pnp and so on means…
or is it better to use a camera and analyze the picture?
thanks for your help!
