MKS A4988 Stepper Driver 1A

/*
The MKS A4988 is a stepper motor driver based on the A4988 chip, commonly used for controlling bipolar stepper motors. To control a stepper motor using the MKS A4988 driver and an Arduino, you'll need to connect the driver's STEP and DIR pins to the Arduino and provide appropriate power supply to the motor.

Here's an example code to control a stepper motor with the MKS A4988 stepper driver:

This code rotates the stepper motor clockwise for one revolution, waits for one second, rotates the motor counterclockwise for one revolution, and then waits for another second before repeating the process.

Connect the MKS A4988's STEP and DIR pins to the Arduino's digital pins 3 and 2, respectively. Make sure to provide an appropriate power supply to the driver's VMOT and GND pins, and connect the motor's coils to the driver's 1A, 1B, 2A, and 2B pins according to the motor's datasheet. Additionally, adjust the A4988's current limit using the on-board potentiometer to match your motor's specifications.
