User serial/pyserial to send messages to an arudino via terminal manually

[Larz60+]

Not plug and play, but a very robust solution:

You could use something like https://www.adafruit.com/product/4471 which uses a Microchip MCP2221A
https://www.microchip.com/wwwproducts/en/MCP2221A uSB to I2C bridge

It can be wired to an Arduino's I2C connectors as follows: https://howtomechatronics.com/tutorials/...h-arduino/

It will take a bit of work to get everything in sync, but software is provided by adafruit.

If you use this approach, you will have the ability to hook multiple devices to the same I2C port.

Here are a couple of I2C tutorials if you are interested in this form of communications (most use python):

These specifically for the arduino:
