A stepper motor is a brushless, synchronous electric motor that converts digital pulses into mechanical shaft rotation. Every revolution of the stepper motor is divided into a discrete number of steps, and the motor must be sent a separate pulse for each step.stepper motor is connected with atmega32 output port pins through a L293D. So when the controller gives pulses with particular frequency to L293D,the motor is rotated in clockwise direction
