What is a ULN 2003 stepper motor Driver
Certainly! Here’s a rephrased version:
The ULN2003 stepper motor driver will be employed to regulate the stepper motor through Arduino.
This particular motor driver module operates using the ULN2003 IC. Occasionally, the motors integrated into the circuit necessitate higher voltage for their functionality.
Within the module, four LEDs are linked, illuminating in correspondence with the signals received by the driver module.
Given that a microcontroller lacks the capability to solely supply power to the motors, a motor driver is utilized in such instances.
Numerous motor driver modules can be found in today’s market, among them is the ULN2003. This 16-pin IC is typically packaged in a DIP (dual inline) format. There exist several alternatives to the ULN2003 driver such as TPIC2701, ULN2001, L293d, ULN2004, and more.
The IC itself serves a broad range of purposes, commonly employed to manage high current LEDs, relays, motors, and specifically, stepper motors. In the context of this article, we explore the utilization of this driver module to operate a stepper motor in conjunction with an Arduino.

About the Code
Within this segment, we delve into the Arduino code pertaining to the stepper motor, elucidating the system’s functionality and the utilization of its inherent functions. Firstly, we incorporate a library to leverage its defined functions. Following this, we instantiate an object, specifically a stepper, and delineate the pins employed.
We designate digital pins 8, 9, 10, 11. In the setup function encompassing both the stepper and Arduino, we establish the motor’s revolutions per minute (RPM) utilizing the setRpm function. RPM denotes the motor’s rotational speed measured in rounds per minute. For demonstration purposes, we set it to 12, yet this value is adjustable to suit your preferences.
Within the loop function, we implement a predefined function to rotate the stepper motor in a clockwise direction to a specified angle. Subsequently, a delay ensues before rotating the stepper motor counterclockwise to a given angle. We trust that this explanation elucidates the code’s operation effectively.
