Arduino UNO Code

// Pin definitions
const int stepPin = 9; // STEP pin on A4988
const int dirPin = 10; // DIR pin on A4988
const int enablePin = 8; // ENABLE pin on A4988 (if used)
const int txPin = 0; // TX pin on Arduino (connected to RX on VC-02)
const int rxPin = 1; // RX pin on Arduino (connected to TX on VC-02)

void setup() {
  // Initialize serial communication for VC-02 module
  Serial.begin(9600);

  // Initialize stepper motor control pins
  pinMode(stepPin, OUTPUT);
  pinMode(dirPin, OUTPUT);
  pinMode(enablePin, OUTPUT);

  // Enable the stepper motor driver
  digitalWrite(enablePin, LOW); // Assuming LOW enables the driver
}

void loop() {
  // Example: Rotate stepper motor
  digitalWrite(dirPin, HIGH); // Set direction
  for (int i = 0; i < 200; i++) { // Rotate 1 revolution (assuming 200 steps per revolution)
    digitalWrite(stepPin, HIGH);
    delayMicroseconds(1000); // Adjust delay for speed control
