It used uln2003a to amplify the control signal from the arduino.
View Uln2003 Driver Board Schematic PNG. Uln2003 ic is one of the most commonly used motor driver ic. The shaft or spindle of a stepper motor rotates in discrete step increments when electrical command pulses are applied to it in the proper sequence.

Wiring diagram and example codes included! (and number of drivers in use). The uln2003 is one of the most common motor driver ics that houses an array of 7 darlington transistor pairs, each the uln2003 ic is needed to drive the motor with an arduino, but they come in convenient and cheap driver boards that are readily available complete with indicator leds.
It's easy to use arduino or other development platform to drive the stepper motor by this diver board.
Uln2003 is a relay driver ic consisting of a darlington array. The mini stepper driver is small size and easy to use. The drive voltage can up to 15v. The driver board accepts a four bit command from any microcontroller and in turn applies the necessary power pulse to step the motor.
