Ok simple get one of those cheap digital voice recorders, that you press a button and it plays a message ,i think its called a spy recorder or somethingget a motion sensor that turns on a LED , or just use comparators connected to the motion sensor and have it switch a transistor which switches the voice recorder . Also, the voice recorder speaker is pretty weak, so I would make an audio amplifier circuit and play it on some big speakers.Also, look around google, there are many projects like this
ideacould i just run leads from the LED that it turns on ton the play button.then so that if it just keeps playing, for the length of the recording i record the same message over and over
