Hi my professor want me to use CCTV Application to control motor outside CCTV Camera, so he told me that i have to wire between stepping motor and driver in CCTV camera , i use digitalRead for get signal 0 1 but i turned my camera from left to right 10 times but my signal not the same pattern .
How can i use those signal for control Motor outside CCTV camera ?
Please draw a block diagram showing the CCTV, the stepper motor and your Arduino.
What signals come from the CCTV, and how are they supposed to inform the motion of the motor?

Shouldn't you go back to your professor and ask him to clarify/explain?
He knows the equipment you have - we don't
He can see how you have it set up - we can't
He can see your code - we can't
He is far better placed to help than we are!

what does "CCTV Application mean?
a computer-software?
what is this driver in the CCTV camera?
Is this a stepper-motor-driver?
what kind of signal?
can you provide a datasheet or a manual of the CCTV-camera that explains this signal?
This highly depends on what the signal is.
Without seeing the signal
or
without a manual that explains this signal
it is impossible to analyse it.
as a general advice. English seems not to be your native language.
Realising this project needs precise information.
I recommend that you write down a very detailed description in your mother-language and then use google-translate to convert your description into english.
I have tested this many many times and it works really well.

That would be another advantage of going to your professor!
It sounds more like you are supposed to use coding in the camera's software to control it's movements.
Or are you supposed to re-wire the camera with an Arduino? That would be a very different project.
If you are supposed to rewire the camera, you would not want to wire the Arduino between the driver and the stepper. You would want to wire the Arduino to the driver and the driver would be wired to the stepper. Either that or you would want to wire your own driver to the stepper motor. You never want to wire a stepper directly to an Arduino. You'll burn it our very quickly.
