Re: l298 python code

Well the connections between the pi and motor drive board look ok and I guess you have power connected to motor drive board because the red LED is lit. when you try to run the motor does that red LED go out ? Have you tried replacing the motor with a volt meter to see if you actually have any volta...

Re: l298 python code
