UNIPOLAR STEPPER MOTORStepper motor is used in this project to control the movement of LASER pointer toward the intruder.
FEATURE:-
The rotation angle of the motor is proportional to the input pulse. The motor has full torque at standstill. Precise positioning and repeatability of movement since good stepper motors have an accuracy of 3-5% of a step and this error is non-cumulative from one step to another.

CONCLUSION
This project is designed to safe ground the boundaries at extreme conditions. Where human intervention is very difficult and save the precious live of our soldiers. It is used to reduce the power consumption of the microcontroller using OS concepts. The direction of the LASER is accurately pointed by alleging the camera with respect to the stepper motor. The power consumption of LASER is reduced by using relays.
