kad Posted October 8, 2005 Report Share Posted October 8, 2005 Is there any sensor which detects the direction in which the person is moving? That is it should produce a pulse if the person is moving in one direction and a negative pulse if he moves in the opposite direction..please help Quote Link to comment Share on other sites More sharing options...
