Communicating with the Arduino is simply over a serial connection provided by the USB or JDY-31 serial pass-through Bluetooth module.

As the continued development of this project I have now designed a slider for the pan tilt mount.
Some picture, videos and development updates are available here: https://www.instagram.com/p/B-KXCTlj_CY/
The slider is made from mostly 3d printed parts, M3 nuts and bolts and 2020 V-slot aluminium extrusion. It uses the same PCB I created for my pan tilt mount which is why I included an extra stepper driver and breakout for another Hall effect sensor.
The CAD STL files are available here: https://www.thingiverse.com/thing:4316563
The 2GT timing belt, 20 tooth timing pulley and 16th microstepping allow the slider to move with a precision of 0.0125mm. The movement speed can be set extremely slow for time-lapses or up to about 200mm/s (in full step mode).
