This code was made to operate 2 gear motors to create a car that demonstrates the capability to turn left, and right as well as go backward and forwards for further info on code and circuitry access link to Tinkercad on the original post (at the bottom).

Thanks.. Tom..

Sorry got this working but for some reason, it requires a laptop connection as a power source I need it to work off the 9V battery instead as it must operate independently. I'm not sure if the issue may be in the battery pack itself or the overall circuitry. Thanks for your help in advance.

Hi, @acemax

@acemax

it requires a laptop connection as a power source I need it to work off the 9V battery instead as it must operate independently.

If you are using a PP3 smoke detector battery like this;

Then you will not get enough power from it to run your robot.

You haven't connected positive of battery to vin pin of Arduino

[acemax]

Once again I would like your advice as I am still unable to operate this car.

[amitf]

Try with a better battery. Or you can use two seperate 9v battery to power motor and Arduino

Can you post the pic of your actual circuit

Ya it will be helpful
