Topic: Can I use a motor without a motor shield (Read 587 times) previous topic - next topic


I just want to know if it is possible to connect a motor to arduino uno r3 without a motorshield.


Without a "motor shield", yes. However you do need to shield an Arduino from the current load that the motor requires. In other words, do not attempt to drive a motor directly from an Arduino pin. You must use another device such as a transistor or perhaps (in some cases) a small relay as a 'switch' that the Arduino pin can activate and leave it up to the device to handle the current to the motor. - Scotty


And a flyback diode to stop the motor zapping the Arduino when it stops...

Have a look at this tutorial on how to run a motor with a transistor.

Please don't PM for technical advice. Firstly my advice is sometimes wrong, and second, in the forum you get a broader, more timely, range of responses.
