Lets say we want to control a basic DC motor (future goal would be a remote controlled car, and if we really went all out, the control signal would come in through a wireless network card), how does one do it with a PC or other?

buy an old 486 with a parellel port.
parellel port is easy to use.

By 'control' do you mean something like proportional control, or is switching it on and off enough for you? And how much current and voltage to you have to control (and with a motor there is the inductive spike, too)? So you probably have to use something between, eg, the parallel port and the motor, or you'll blow the parallel card.

What would you use to control say a DC motor under 24 volts? Is there a circuit diagram available?
you will need transistors and relays or large transistors.

proportional control can be simulated by quickly pulsing the parelell port on and off (pulse width modulation).
Check out the Basic Stamp or other microcontrollers.
The controller can do the real world I/O while the computer does the computing.
It will take some programming, but the Stamp can take commands from the computer and provide real world data when queried.
