Code Documentation

#include <Stepper.h>

// Define the number of steps per revolution for your motor
#define STEPS_PER_REV 200

// Initialize the stepper library on the pins connected to the motor
Stepper stepper(STEPS_PER_REV, A5, A4, A3, A2);

// Define the button pin
const int buttonPin = 2;

// Variable to store the button state
int buttonState = 0;

void setup() {
  // Set the speed of the motor in RPM
  stepper.setSpeed(60);

  // Initialize the button pin as an input
  pinMode(buttonPin, INPUT);
}

void loop() {
  // Read the state of the button
  buttonState = digitalRead(buttonPin);

  // Check if the button is pressed
  if (buttonState == HIGH) {
    // Define the number of steps for each interval
    int stepsPerInterval = 50; // Adjust this value as needed

    // Rotate the motor a specific number of steps in one direction
    stepper.step(stepsPerInterval);
    delay(1000); // Wait for a second

    // Rotate the motor a specific number of steps in the opposite direction
    stepper.step(-stepsPerInterval);
    delay(1000); // Wait for a second
  }
}

This code initializes the stepper motor and the arcade button. When the button is pressed, the stepper motor rotates a specific number of steps in one direction, waits for a second, and then rotates the same number of steps in the opposite direction. The speed of the motor is set to 60 RPM.
