The ULN2003 is a simple and reliable motor driver designed for controlling unipolar stepper motors like the 28BYJ-48. It helps your microcontroller (Uno, Nano, Mega, etc.) send enough power to the motor while protecting it from damage. With easy plug-and-play connections and built-in safety features, it's a great choice for beginners working on robotics, automation, or motion control projects.
