This is code for my version of DIYbio Orbital Shaker V1.0 from https://www.thingiverse.com/thing:2633507
Which using motion_link_new.stl, motion_link_motor.stl and Shaker_PlatformSupportV2.stl from https://www.thingiverse.com/thing:6132449
Main difference is that I am using ESP32-C3 dev board instead of Arduino that enables me to use WIFI and control and suervise shaker via web browser, any ESP32 should work.
- input and output pins, I don't have the same esp32 as on schematic, so pinout in my code is different. Just set pin numbers for motor and potentiometar correctly
- Set Vref on DRV8825 to limit maximal current
- Potentiometar takes over on change, Web control takes back on change from it.
- Add code to set M0, M1, M2, Enable for DRV8825 from web interface
