1: Go from the pins to the motor. This only works if it's a _really small_ motor that's rated for your processor's VCC and drive current capability. 2: Amplify the pin outputs, and connect the motor to the amplifiers. This is a nice general-purpose connection. 3: Get a stepper driver that contains logic and amplifiers, and supply it with enable, direction, and clock from the microprocessor. This offloads the processor, but costs more.
Connections one and two require that you sequence the pulses to the motor correctly, but take less circuitry. Connection 3 is easier, but requires that you pay $$ for the drivers.
