Help with motion detection idea Answered

I had an idea for a dramatic halloween set up where the porch light turns off as the person approaches the door and turns back on again when they leave. 

First off I don't even know if this is possible. I assume I would need a PIR motion detector and arduino to make this work. I have had some experience with very basic electronics but never anything like arduino so I wouldn't know how to begin programming something like this. I'm guessing I wouldn't be able to use the actual porch light so I plan to set up another light bulb.

I would love any advice as I want to make this idea happen but I simply don't know how to approach it. Thank you!

No need for a micro controller. You can take an existing motion detector and a Power Switch Tail and make what you need. Test the output of the motion detector and see what the voltage is. You may need to pass that through a transistor switch to allow the 3V-12V needed to activate the power tail or deactivate it as needed. You may even be able to use a motion detector made for outdoor lighting and modify it to turn the light off rather than on.

I love your idea to simply switch an outdoor motion detector to turn off, brilliantly simple!Thanks a lot, I hope I'll be able to get it to work in time for Halloween!
