The ULN2003 Stepper Motor Driver Module is small size & ease to use electronic module, it used ULN2003 Chip to amplify the signal from the micro controller, Input voltage max 15v
Logic Control Voltage: 3 to 5.5v
Motor Supply Voltage: 5 to 15v
Can Sink 500mA from 50v supply,(beter used voltage driver under 15 volts)
Operating Temperature: -25 degrees Celsius to +90 Degree Celsius
Stepper motor has convert pulse to angle displacement. So if you give stepper driver a certain PWM signal, it will drive step motor to a certain angle. you can control the angle the stepper moved by the number of the pulse.
And you can also control the speed of the stepper rotate by the frequency of the pulse.
Controlling the signal to drive a 28BYJ48 stepper to rotate 1/4096 circle.

& in the following usage it will run, and then you must know how to drive a stepper.
The stepper motor stopped when pushed the stop_button. It also can be changed to control the stepper motor to counterclockwise or clockwise rotation.
