giving pulse to stop stepper motor

[Monireh]

Hello 

i am working in a project using labview 8.2 which  tracks the sun using stepper motor based on equations.

once the program will be started, it'll assume that  the solar panel which will rotate by the motor is in east direction so based on the date and the time it will rotate till it finds its correct position. it moves with steps 24 hours which is waste of power so i want to modify the program such that it will stop at night and again start rotating the day after.   

i was wondering if you can please help me

Looking forwaed to recieving from you

Hello,

Hi Monireh,

do you already get the signal for sunset and sunrise? Which of your indicators show this information?

How do you control the motor? Is it already implemented?

Try to help.
