As the above YouTube video shows, circuit now has 3 stepper motors under individual control. Serial IO commands can be sent to set each of the 3 motor positions independently.
Motors will be used for Altitude, Azimuth and focus.
Yes this progress took many modifications both hardware and software as well as much swearing and coffee.
Now I am happy to end another day. Next aim is to put the motors on a timer control so I can control their speed. Then its on to mounting them on the actual mount itself.
Until then, enjoy!
