Easy bipolar motor control? Is here some easy way to control bipolar motor
 without using any other external devices, drivers or shields? I have small motor from CD-ROM so I expect it's low voltage. By control I mean just turning clockwise  and anti-clockwise and speed. I'm looking for easy to make circuit not just direct control from Arduino.
No. You cannot directly drive any bare motor directly from an Arduino without any external components. To do so will damage the Arduino.

You need a motor driver (or at least some transistors and diodes etc) to control the motor.
