[Controller] Routing Custom Arduino to Unreal

Hey guys,
Noob here.
I have a custom controller I made with an Arduino board that functions simply:
You spin the motor, and in the output window of Arduino, you get a value on how fast you spin it.
I would like to route this EXTREMELY simple thing to Unreal, so that when the spin value is greater than 10, it moves you** at x speed.
**You is a first person character

If there are any plugins, that would be great. Otherwise, I can “sort of” program.

I really appreciate anybody who answers!
