❌ What they usually lack:

delay(1000);

Simulation Process

1. Double-click the Arduino in Proteus. Load the compiled .HEX file (generated from Arduino IDE).
2. Click the Play button (bottom left) in Proteus.
3. Observe the stepper motor rotating. You can change DIR pin state to reverse direction.
4. Use Proteus oscilloscope on outputs 1A and 1B to see the chopped sine wave (microstepping) or square wave (full-step).

Issue 4: No current sense (SENSE pins)
Real A4988 uses sense resistors for current limiting; the library ignores them entirely. Double-click the Arduino in Proteus
