I have a 12V motor, which I need to control from my Raspberry Pi (through the RaspiRobot Board). However, the RaspiRobot Board gives me only 3.3V for the motor. At the same time, I have a 12V adapter (that came with the motor).
What I now require is, that I power the Motor from the 12V Adapter, and Switch it On/Off from the RaspiRobot Board (with the 3.3V output).
The RaspiRobot Board also lets me Switch the polarity, so it would be better if I could control the direction of the motor in this way too.
