hi
i need to control a 20x20 field of small electro magnets with linux. every magnet should be controllable individually, but just on and off.
is it possible to use the serial port for this amount of devices?
how can i control them without building special hardware for the pc?
because i'm a little enoyed to put together 400 small electro magnets, are there any standart parts (magnetmatrix) available?
every advice is welcome.
