Top level objects communicates with incoming outgoing Graphical Interface/Central Computer Communicates with the door/choke, waveguide, magnetron, and cooking cavity. Incoming messages are from the user (power, timing, etc.), also from the door, which tells the GUI whether the waveguide is safe to activate. Outgoing signals tell the magnetron to begin making the waves, the cooking cavity to spin, displays time on the screen. Door Communicates with the GUI to ensure the microwave can only activate if the door is closed or after engaging the choke. Only incoming message comes from the choke which tells if the door is opened or not.
