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.
Taking a guess here, the current this motor requires will be exceeding the safe operation limits of the Arduino's GPIO pins. Furthermore without a flyback diode the voltage spike across the motor (an inductive load) when the current is reduced/switched off might kill the GPIO pin.
You will need a motor driver or transistor with flyback diodes to operate it.
This is a nice tutorial that has it sorted out for a CD ROM brushless motor.
