28BYJ-48 5V Stepper Motor with ULN2003 Step Motor Driver Board

The 28BYJ-48 stepper motor comes with a 5-pin connector that fits well in the driver board’s motor connector. The driver board has two pins for the power supply which are labelled (-) and (+5-12V). The board’s (-) pin must be wired to the Arduino’s GND pin. 

The ULN2003 stepper motor driver board happily accepts a 4-bit command from almost all microcontrollers and in turn applies the requisite drive pulses to step the motor.
