Arduino 3: Controlling Stepper Motor Using Arduino | Unipoloar and Bipolar Stepper Motor #arduino

This is a demo video on how to control a Unipolar Six wire Stepper Motor using an arduino and ULN2003 circuit.
ULN2003 consists darlington pair of transistors that are useful in controlling stepper motor.
same circuit can be used to control bipolar stepper motor also.
the motor i have used here is a salvaged stepper motor from an old printer and it cost me half of a dollar (nearly 30 rupees in indian currency) .
you can gather such motors and can use it to build a very cheap 3D printer or DIY CNC machine..
