Thanks CrossRoads & MarkT
Just to make sure I understand:
If I take a line out of one of the digital pins it will get treated as a road to a ground connection and because it wants 9V it will take 9V and this will fry the board. If I put a 180? resistor between the pin going into a transistor this will limit the flow that the motor is trying to take(?) and allow an acceptable amount of current to charge up the transistor and then pass into the motor when it's got enough charge to discharge?
Then how do I earth this larger current from the motor negative line as it will surely have to go back into the Arduino? Do I put another resistor in before going to earth to step it down? I really am very new to the electronics bit of this.
Also if I use pin 9, 10 or 11 with analogWrite, can I limit the amount of electricity sent to the motor by limiting the flow output programmatically?
