What is Arduino Microcontroller ??
 It is Open Source (Hardware + Software) and single board microcontroller.
 Work as, both Master or Slave device.
 Arduino = internally CPU+RAM+IO interfaces + programmer
(AVR,AVRISP,USBISP,USBASP) .
 In 2005, a project was initiated to make a device for controlling
student-built interactive design projects that was less expensive
than other prototyping systems available at the time.
 Founders Massimo Banzi and David Cuartielles named the project
after Arduin of Ivrea and began producing boards in a small factory
located in Ivrea.

Necessary Things to done a Project with
Motor
 Motor Driver : To control the direction of the spin of DC motor, without
interchanging the leads, you can use a circuit called an H-Bridge(Motor Driver).
An H-bridge is an electronic circuit that can drive the motor in both directions.
 Example : L298, L293 ,ESC etc.
