Motion sensor to motor circuit setup
It is basically to track whether or not something has exited a large box rather than its entry, this is so that on exit of the box the motor will change the the internal environment but not be triggered by entry, only on an additional exit.
I am confortable with the mechanical side of this project however I am a novice to electronics and any help you could offer on the subject would be fantastic.
If you need more information please feel free to ask.
I could insert a quick sketch if this would help.
