I want to control PWM fan speed by +/- keyboard keys using Simhub

Hello,

I have planned to control a PWM fan with an Arduino Pro micro or Leonardo clone. I have everything coming from an old button box and a 120mm PWM fan coming from my old computer.

My project is to control the fan speed using my keyboard in a 1st time and then to control it with my stream deck in a 2nd time.

How can i affect keyboard keys to increase/decrease fan speed in Simhub?
