Motor Driver(L298N)

This module allows for control over the speed and direction of motors. It can operate two DC motors or one stepper motor.

Specifications

• Input Voltage: 9V ~ 12V
• Speed control via PWM signal
• Direction control with digital signals

Example Required Hardware

• Arduino board
• Jumper cables
• Power supply (9 ~ 12V, battery or adapter)
• DC motors
• L298N motor driver

Connection

	OUT1	Connect
	OUT2	Connect

Example Code

This example demonstrates gradually decreasing the motor's speed until it stops and then reversing direction.

const int IN1 = 8;
const int IN2 = 7;
const int ENA = 9;

void setup() {
  pinMode(IN1, OUTPUT);
  pinMode(IN2, OUTPUT);
  digitalWrite(IN1, HIGH);
  digitalWrite(IN2, LOW);
  analogWrite(ENA, 255);
  delay(2000);
  analogWrite(ENA, 170);
  delay(2000);
  analogWrite(ENA, 85);
  delay(2000);
  analogWrite(ENA, 0);
  delay(2000);
  digitalWrite(IN1, LOW);
  digitalWrite(IN2, HIGH);
  analogWrite(ENA, 255);
  delay(2000);
  analogWrite(ENA, 170);
  delay(2000);
  analogWrite(ENA, 85);
  delay(2000);
  analogWrite(ENA, 0);
  delay(2000);
}

void loop() {
  delay(100);
}
