arduino leonardo single axis steering wheel

[cr0wl]

Hello 
today i got my arduino leonardo and i want to make steering wheel using potentiometers, but since i dont have full "equipment" but only 1 potentiometer, for beggining i want to make only 1 axis joystick, (x axis or whatever is needed for steering in PC GAMES like euro truck simulaotr 2), i tried codes on internet  but i had issues with them like deadzones and so. i think that is because i have only 1 potentiometer but those codes are intended for steering, breaking, force feedback and so..., and because im full noob,scrub with arduino i need help with making single axis controller, i connected potentiometer (10k 300°) and everything, i just really dont know anything about programming it
