So i'm pretty new to this.
i want hook up a couple of computer cooling fans to my sim.
i want to be able to match the fan speed with the speed im going.
there are plenty of apps that extract data from the game.
my question is how do i extract that speed number and input into the arduino?
Then im guessing i can just:
map (min speed, max speed)(min voltage, max voltage)
through a 24v relay
Any help would be much appreciated, even terms to google.
thanks
