🔹 Technical Specifications

🔹 Pin Configuration & Wiring

// Safe Motor & Air Pump PWM Speed Control using L298N Driver
// Tested for Arduino Uno & ESP32 (with ESP32 ledcWrite)

#define ENA_PIN 9   // Connect to L298N ENA (PWM speed control)
#define IN1_PIN 8   // Connect to L298N IN1 (Direction / ON)
#define IN2_PIN 7   // Connect to L298N IN2 (Direction / OFF)

void setup() {
  pinMode(ENA_PIN, OUTPUT);
  pinMode(IN1_PIN, OUTPUT);
  pinMode(IN2_PIN, OUTPUT);
  
  // Initialize driver in OFF state
  digitalWrite(IN1_PIN, LOW);
  digitalWrite(IN2_PIN, LOW);
  analogWrite(ENA_PIN, 0);
}

void loop() {
  // Soft start: ramp up speed to prevent inrush current spikes
  digitalWrite(IN1_PIN, HIGH);
  digitalWrite(IN2_PIN, LOW);
  
  for (int speed = 100; speed <= 255; speed += 15) {
    analogWrite(ENA_PIN, speed);
    delay(50);
  }
  
  delay(3000); // Run motor at full speed for 3 seconds
  
  // Coast to stop
  digitalWrite(IN1_PIN, LOW);
  digitalWrite(IN2_PIN, LOW);
  analogWrite(ENA_PIN, 0);
  
  delay(2000); // Pause for 2 seconds
}
