Hello guys I was looking for a circuit to make a door open when a person stands in front of it after he gets in it should again open when the person is standing behind the door note that after the door opens at the delay of 5 seconds the door closes.PLEASE anyone help me
 
You will probably just need to adapt something like this: **broken link removed**
to detect someone by the door.
I would think the fitting of the actual door opening mechanism (electric motors, mechanical linkages etc) is going to be more of a problem than the 'circuit'!
What are you intending to do for this part of the project?
