In the functions palette Arduino > Low Level there are PWM functions. If the DC motor will only rotate in one direction then all you need is, these functions . If you need bidirectional rotation you will also need to use a digital pin to set the direction.

You need to supply more information before I can provide additional guidance.
Who is the manufacturer and what is the DC motor's model number.
What Arduino shield will you be using to drive the DC motor.
Originally you said DC motor. Now you say servomotor. Do you mean a RC Servo?
What is the application? How will the DC motor be used?

ok here are the informations you asked
-I'm commanding a car and i'm using a motor for thepropulsion (moving forward and back ) and i think i will need a servomotor for the direction control
-the motor has nothing indicated on it !!
-i have arduino MDK because i want to command through android

Unless you have the Android communicating with LabVIEW, you can't use LIFA to do this.

Plese provide a link tothe surce for the car.
I don't see how you will gain anything by using Labview with your car , robot. If you will be using either either an Android Phone or Ttablet to control your car then the preferred communication medium is Bluetooth.

Sorry, I can not help you, You haven't told me the make and model number of the DC motor yuou are using. I need this information to determine the current and voltage rating of the motor. Then based on current and voltage ratings I could recommend a motor shield to use with your Arduino Megs ADK and your DC motor.
The following information is not a recommendation. Howevr, the links can help you get started with your project
Here is a link to a typical motor shield.
<http://www.adafruit.com/products/81>
Here is a link to some bacgroud information and a "How To" for the Adafruit Motor shield.
<http://www.ladyada.net/make/mshield/use.html>
Here is a link to a clone of the Adafruit Motor shield.
The advatage of this clone is it is assembled. Whereas you would need to assemble the Adafruit Motor Shield. Adafruit Motor Shield clones are also available on Ebay at attractive prices.
