How to pull data from stellarium to arduino

Hello crew, i want to pull data from stellarium software to my arduino serial monitor , anyone have related solutions.

Thanks in advance.

Hello,
do you have a complete system description?

At this stage I'm using arduino mega , i just want to print targeted object Alt&AZ data in arduino serial monitor form Stellarium.

Hello
Do you have a Stellarium interface specification ?

Yeah i gone through LX200 protocol sheet, i tried few codes with mega to print RA& DEC data, I'm looking for simple codes & flow for printing alt az data.

Then provide information on how you get the data from your software! Does the software have the ability to output the information through a serial connection?

I'm using this code , this one included with many extra lines , but i'm trying to get the data from stellarium software specific data only.
