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 Python program.
8. Run the Python program.

Python Program

from machine import Pin
import utime
 
m1 = Pin(5, Pin.OUT)
m2 = Pin(4, Pin.OUT)
m3 = Pin(3, Pin.OUT)
m4 = Pin(2, Pin.OUT)
 
en1 = Pin(6, Pin.OUT)
en2 = Pin(7, Pin.OUT)
 
en1(1)  # motor 1 enable, set value 0 to disable
en2(1)  # motor 2 enable, set value 0 to disable
 
while True:
    #Both Motor in forward direction
    m1(1)
    m2(0)
    m3(1)
    m4(0)
    utime.sleep(1)
    #Both Motor in Reverse direction
    m1(0)
    m2(1)
    m3(0)
    m4(1)
    utime.sleep(1)
    #Both Motor in stop position
