I am trying to connect two DC motors to a L298N. They are 12V motors but the datasheet says that they can work on 6V-15V range. Because of this, I decided to use a 9V Duracell battery to go to the L298N. I connect this battery to Arduino and get the (v that I feed to the L298N from the Vin pin.
The issue that I have is that when connecting only one motor it works properly, but when both of the motors are connected they don't rotate fully but kinda stutter. What is the issue? Am I not supplying enough voltage, enough current or is there any other problem? This is for a school project and they have set a very limited budget for what we can use, so I cannot afford any fancy solution. Thank you in advance.
