Because of the system's stability and durability, the 28BYJ-48 Stepper Motor and ULN2003 Stepper Motor Driver is a common combination of stepper motor and stepper driver. The 28BYJ-48 stepper motor is the most commonly used stepper motor due to its small size, 12V power supply (which can be supplied by any controller), and high level of control. Driver Module ULN2003 Stepper Motor Driver Board is used to drive and control stepper motors. The ULN2003 Stepper Motor Driver Board drives the 4-phase 5-wire stepper motor with the ULN2003 DARLINGTON ARRAYS. An ordinary ULN2003 chip can be used to drive the 5 Line 4 Phase, which can also be connected to the phase 2 development board to facilitate the usage of a direct plug and easy-to-use stepper motor. These stepper motors draw a lot of currents, hence a driver IC like the ULN2003 is required. The major function of the ULN2003 is to amplify the control signals from the Arduino so that they can be used to operate the 28BYJ-48 Stepper Motor. If you send a specific pulse signal to the ULN2003 stepper driver, it will drive the step motor at a specific angle. The number of stepper motor driver pulses is used to control the stepper motor movement angle. The frequency of the pulses can also be used to adjust the rotational speed of the stepper motor.
