I wanted to clarify regarding using 12 volt battery and having 2 motors that I think max voltage is 3 volts. If i use PWN and step down the voltage to 3 volts will L298N produce a lot more heat to step the voltage down?
Probably in this case would be the best just to get two separate power supplies 9 volts for arduino and 4.5 volts for the motor drive to supply 3 volts for each motor. Unless i get better motors that support 6v - 9v then i can use the 12 volts battery for both arduino and motors.
