I am doing a very basic project. I ordered the robot chassis from here(http://www.ebay.com/itm/2WD-Car-Chassis-Kit-Smart-Robot-Speed-Control-Encoder-Battery-Box-For-Arduino-/292090853676?hash=item4401f8b92c:g:4w8AAOSwIWVY-BbK)
A 9V battery A L298N hbridge module (For controlling motors) Two dc motors An arduino uno
My problem is that when I try to run both dc motors at once, one gets more power(almost 90%) than the other resulting in one wheel rotating and other just moving super slow.
I tried running simpler dc motors and they worked fine(both)
When running each motor individually, everything works fine.
I think I might need a 12V battery, but I would like to know how is the power distributed.
