Can i connect 6v DC motor and 12v DC motor, or 6v DC and 12V stepper to adafruit motor shield v1, and an external 12v power supply? also, how does it determine how much voltage needs to be supplied to a motor? is it done by code, when we set the speed of the motor, or the frequency?
do i have to take care of how much voltage i am supplying to the motor shield?
