I have an adafruit motor shield connected to arduino uno, i need to control two dc motors of different voltage rating 1) 6v dc motor and 2) 12v dc motor.
can i power my shield with 12 v supply to run these two motors.

Yes, you just set the pwm maximum value at 50% for the 6volt motor. Bear in mind that you won't get the full 12 volts to the motor due to driver losses.

It seems OP has the old v1.2 shield according to a link in a previous thread.
The one with <= 600mA L293D chips.
In that case about 9volt is needed for the 6volt motors anyway.

thank you, i'll check that, but right now i'm controlling it using another motor driver over arduino shield and using analog pins as digital pins :slight_smile:
