With the hardware layout designed in Proteus, you need code to drive the simulation. Below is a clean, non-blocking Arduino sketch designed to test both speed and direction changes.
The is the command center, receiving low-voltage signals from the MCU (like an Arduino UNO) to control the Stepper Motor .

The A4988 is a microstepping driver for bipolar stepper motors, widely used in 3D printers, CNC machines, and robotics. It handles complex pulse-width modulation (PWM) switching, providing full, half, quarter, eighth, and sixteenth-step control.
This comprehensive guide explains how to acquire, install, and use the to simulate stepper motor drivers in Proteus VSM, ensuring you can design and test your circuits before soldering. What is the A4988 Driver and Why Use a Library?
Microstep selection pins. By configuring these pins HIGH or LOW , you can change the step resolution from full-step down to 1/16th of a step.
