28BYJ-48 Stepper Motor with ULN2003 driver card

The 28BYJ-48 stepper motor is a small, cheap, 5 volt geared stepping motor, perfect for Raspberry Pi robots. It can turn according to specific angles known as steps. It can rotate continuously like a regular DC, but the ability of doing step turns makes it more preferable for creating much more complex projects in robotics and with Raspberry Pi. It comes with a ULN2003 driver card, to be controlled more easily.
