Hooking up a pager motor...

I have a pager motor that I want to try to run off my Arduino.

It runs at 1.3V @ 70mA.

Do I need to put a resistor in between the Arduino and the pager motor? I know the Arduino supplies 5v or ~3v.

Thanks for any help...

The problem is the motor's 70ma current requirement which is at least double the maximum current that can safely be drawn from an Arduino output pin. You will have to find another method to drive the motor, either transistor switching or some other method like an opto-isolator that has a 70ma or greater output current rating.

How do we know the maximum output for the Arduino?
(If that is a newbie question...guilty as charged)

Section 28 of the data sheet for the AVR microcontroller states the DC specifications:

As mentioned above, I would recommend a simple one-transistor driver circuit for the pager motor. No doubt similar motors are found in mobile phones. Remember to add a back-EMF protection diode, because this is an inductive load.
