This is a circuit to launch missiles from the 1983 movie Wargames. Instead of requiring both people to turn their keys we only require one person to turn the key for launch.
This next circuit is a security system which turns on a porch light at night if motion is detected.
The next circuit is a 2 story elevator system. There are two buttons in the elevator: Up and Down. If the elevator is on the lower floor and the Down button is pressed then the Power stays Off but the direction of the motor is set to Down. There is a floor sensor which returns the location of the elevator. The motor direction indicates which direction the elevator will go if the Power is turned on.
This next circuit is a full adder solution.
