⚙️ 8051 Stepper Motor Interfacing

This repository demonstrates how to interface a stepper motor with the 8051 microcontroller using the ULN2003 driver to handle the extra current required to run the motor. The project includes complete assembly code, Proteus simulation files, and documentation, along with screenshots and photos from testing.

📦 Project Overview

The project showcases the integration of a stepper motor with the AT89C51 microcontroller, part of the 8051 family. The stepper motor is driven via the ULN2003 Darlington transistor array, which provides the necessary current amplification to drive the motor efficiently. The Proteus simulation files enable you to visualize and test the functionality before implementing it on hardware.
