Hi all, I'd like to control a peristaltic pump from a PC through an Arduino. There are Kamoer pumps with wifi but they were too expensive, so i settled for a Kamoer KCM-ODM which includes a 2802 pulse generation control board already connected to buttons, display and a rotary encoder. [pump] I t…

[image] pepeugalde: and P1-P4 came pre-connected to buttons, encoder and display. I'd prefer to leave them connected as an option to control the pump physically. just put an Arduino controlled relay in parallel to those buttons.

Kamoer 2802 control board, need help connecting

from a PC through USB is fine.

It appears that you can control this pump with rs485 communication lines.
I think you could connect it to your computer with a USB to RS485 bidirectional converter.
