hello Jasem
so I'll try to modify the driver and remove the parts that I think are useless.
But where can I see the commands in the driver, that it sends to the arduino, because I need to find the "home" command of the rotator, and the command to give an angle from the serial terminal of the IDE, to control the modicication of the code without going through kstars for my tests.

And thank you for the link to the other rotator drivers, but is there also one online for the arduino.

Thanks again.
