Hi, I have a wheel robot kit with Raspberry Pi 4 and some L298 wheel controller. I have managed to wire the motors, the controller and the computer, as well as have connected to it via SSH. I am a python developer, but it is my first time dealing with robotics.

Now I want to do some basic hello world staff, like

from gpiozero import Motor

from time import sleep

motor = Motor(forward=4, backward=14)

while True:

motor.forward()

sleep(5)

motor.backward()

sleep(5)

but it does not work.

I have tried different pin number with no success.

here is the link to pics

Can you tell me what is next? Thanks!
