Arduino Example Code

Use this simple code to test two DC motors with L298N motor driver.

#define ENA 5
#define IN1 8
#define IN2 9
#define IN3 10
#define IN4 11
#define ENB 6

int motorSpeed = 180;  // 0 to 255

void setup() {
  pinMode(ENA, OUTPUT);
  pinMode(ENB, OUTPUT);

  pinMode(IN1, OUTPUT);
  pinMode(IN2, OUTPUT);
  pinMode(IN3, OUTPUT);
  pinMode(IN4, OUTPUT);
}

void loop() {
  // Forward
  analogWrite(ENA, motorSpeed);
  analogWrite(ENB, motorSpeed);

  digitalWrite(IN1, HIGH);
  digitalWrite(IN2, LOW);

  digitalWrite(IN3, HIGH);
  digitalWrite(IN4, LOW);

  delay(2000);

  // Stop
  stopMotors();
  delay(1000);

  // Backward
  analogWrite(ENA, motorSpeed);
  analogWrite(ENB, motorSpeed);

  digitalWrite(IN1, LOW);
  digitalWrite(IN2, HIGH);

  digitalWrite(IN3, LOW);
  digitalWrite(IN4, HIGH);

  delay(2000);

  // Stop
  stopMotors();

5V_EN Jumper Note

Many L298N modules include a 5V_EN jumper.

• If motor supply is around 7V–12V, the onboard regulator can provide 5V output on many modules.
• If you remove the 5V_EN jumper, you may need to supply external 5V logic power.
• Do not connect high voltage directly to Arduino 5V pin.
• For safe use, check the module marking before powering the circuit.

Important Notes / গুরুত্বপূর্ণ নোট

⚠️ Use a separate motor power supply for motors.
⚠️ Arduino and motor driver must share common GND.
⚠️ Do not exceed the motor driver current rating.
⚠️ L298N can become hot during high current motor operation.
⚠️ This module has voltage drop, so motor output voltage may be lower than input voltage.
⚠️ For small battery-powered robots, use properly charged batteries.
⚠️ Remove ENA/ENB jumper if you want PWM speed control from Arduino.
⚠️ Keep motor wires away from sensor signal wires to reduce noise.
⚠️ Product PCB color, terminal color and component layout may vary depending on stock batch.
