  analogWrite(motorPin, 128);
  delay(1000);

  analogWrite(motorPin, 64);
  delay(1000);
// Set motor speed to 75% (high speed)
  analogWrite(motorPin, 192);

// Define motor pins
const int motor1Pin = 18;
const int motor2Pin = 19;
const int motor3Pin = 21;
const int motor4Pin = 22;
void setup() {
  // Initialize motor pins as outputs
  pinMode(motor1Pin, OUTPUT);
  pinMode(motor2Pin, OUTPUT);
  pinMode(motor3Pin, OUTPUT);
  pinMode(motor4Pin, OUTPUT);
// Initialize PWM channels
  ledcSetup(0, 50, 16); // Channel 0, freq 50Hz, 16-bit resolution
  ledcSetup(1, 50, 16);
  ledcSetup(2, 50, 16);
  ledcSetup(3, 50, 16);

void loop() {
  // Set motor speeds to stabilize the quadcopter
  ledcWrite(0, 128); // Motor 1: 50% speed
  ledcWrite(1, 128); // Motor 2: 50% speed
  ledcWrite(2, 128); // Motor 3: 50% speed
