Hub motor controllers

Hello everyone,

I was working on a project to get data from hub motor controller of an electric scooter.

The Hub motor controller on the scooter provides very vital information such as speed,RPM of motor, battery consumption, range, battery status, using a set of wires which are +ve, -ve, control , tx & Rx , they are connected to a LCD display (I have attached the wire diagram) but I wanted to get these information using Arduino on my computer, I have no idea of how to get these inputs from the motor controller.
Please help me on this as I am a newbie in this.
Thanks

What have you tried? Post your best effort, after reading and following the instructions in the “How to use this forum” post.

Alternatively, you can post on the Gigs and Collaborations forum section. You may be asked to pay for the help.

Is there possibly a kind of diagnostics connector that can be used by a Pc? Like at cars?
