I built a lego robot, I am using linux as operating system. I also have a
simple circuit connected to the printer port that has 4 switches. (I can
activate or deactivate 4 circuits) .
My robot has 2 motors, and i need to forward or reverse each of them.
Thsi leaves me wit 2 switches per motor. Now how can I do forward and
reverse? One way is easy wiht a one switch, but when i try to add reverse i
get a short circuit
