Project Details
How It Works
How It WorksThe project works by using an Arduino to send STEP and DIR signals to the A4988 driver. The A4988 translates these signals into precise current pulses to the stepper motor coils, controlling rotation in discrete steps. The Arduino code generates pulses on the STEP pin (with delays to control speed) and sets the DIR pin high or low for direction. The A4988 handles current regulation, microstepping, and protects the motor from overcurrent. A 100µF capacitor across VMOT and GND provides stability for the motor power supply.
Prerequisites
Basic understanding of Arduino programming (digital output, loops, delays). Familiarity with basic electronics concepts (voltage, current, ground). Ability to read simple circuit diagrams. No prior experience with stepper motors required.
