Arduino is a great starting point for electronics, and with a motor shield it can also be a nice tidy platform for robotics and mechatronics. Here is a design for a full-featured motor shield that will be able to power many simple to medium-complexity projects.
Here's the code, embedded using codebender!Try downloading the codebender plugin and clicking on the Run on Arduino button to program your Arduino with this sketch. And that's it, you've programmed your Arduino board!You can keep playing with that by clicking the 'Edit' button and start making your own modifications to the code. For example try to combine parts of code to move both motors simultaneously.Try to use analogWrite(pin, PWM value) instead digitalWrite(pin, HIGH/LOW) to control the speed of motors!
Each chip contains two full H-bridges (four half H-bridges). That means you can drive four solenoids, two DC motors bi-directionally, or one stepper motor. Just make sure they're good for under 600 mA since that's the limit of this chip.There's a PWM input per driver so you can control motor speed. Runs at 5V logic. Good for motor voltages from 4.5V up to 36V!

This wont work well for 3V motors. The motor voltage is separate from the logic voltage.The L293D has two +V pins (8 and 16). The pin '+Vmotor (8) provides the power for the motors, and +V (16) for the chip's logic.Normally we can connect both of these to the Arduino 5V pin. We used a powerful motor, or a higher voltage motor.

So we provided the motor with a separate power supply using pin 8 connected to the positive power supply and the ground of the second power supply is connected to the ground of the Arduino.
