Control Arduino servo motor with Unity

Hi everybody!
I'm trying to control my servo motor just using Unity. I've created some buttons in Unity 3D in order to control the angulation of the servo (button 1 is 30°, button 2 is 60° etc.). The problem is that I can't find any C# script to do something like this. Can someone help me? Thank you!
