Circuit

Steps

1. Make sure the components are working properly.
2. Connect the 12V Battery to the L298N Motor Driver.
3. Connect the ENA, IN1, IN2, IN3, IN4, ENB pins to the Raspberry Pi Pico board pins GP7, GP5, GP4, GP3, GP2, GP6 properly.
4. Connect the DC motor pins to the motor driver output pins.
5. Connect the ground connection respectively.
6. Check the Electrical Circuit.
7. Check the Arduino program.
8. Run the Arduino program.

Arduino Program

int motor1pin1 = 2;
int motor1pin2 = 3;
int enPin1 = 4;

int motor2pin1 = 5;
int motor2pin2 = 6;
int enPin2 = 7;


void setup()
 {
  pinMode(motor1pin1, OUTPUT);
  pinMode(motor1pin2, OUTPUT);
  pinMode(enPin1, OUTPUT);
  digitalWrite(enPin1, HIGH);

  pinMode(motor2pin1, OUTPUT);
  pinMode(motor2pin2, OUTPUT);
  pinMode(enPin2, OUTPUT);
  digitalWrite(enPin2, HIGH);

}

void loop() 
{
  digitalWrite(motor1pin1, HIGH);
  digitalWrite(motor1pin2, LOW);
  digitalWrite(motor2pin1, HIGH);
  digitalWrite(motor2pin2, LOW);
  delay(1000);

  digitalWrite(motor1pin1, LOW);
  digitalWrite(motor1pin2, HIGH);
  digitalWrite(motor2pin1, LOW);
  digitalWrite(motor2pin2, HIGH);
  delay(1000);
