I put this 3D tachometer together as part of a larger project.
Feel free to use or modify it for your own stuff.

The package file:

The script:
using UnityEngine;
using System.Collections;
public class Tachometer : MonoBehaviour {
public Transform needle;//The needle object of the meter
public static float inputValue=0f;// The value provided by the player
public float inputMin=0f;// The minimum expected value for the meter's lowest reading
public float inputMax=0f;// The maximum expected value for the meter's highest reading
float inputTemp=0f; //Temporary number
float currentReading=0f; // The angle of rotation for the needle object
public float minReading=0f;// The minimum angle of rotation for the needle object
public float maxReading=0f;// The maximum angle of rotation for the needle object
float testNum=0;// The number used to test the
bool testTurn=true;// Used to cycle the test number
public bool testing=false; //Are we testing?
void Start()
{
if(testing)
{
testNum=inputMin;
}else{
inputValue=inputMin;
}
}
void Update()
{
if(testing)
{
if(testTurn)
{
testNum=testNum+0.1f;
if(testNum>=inputMax)
{
testTurn=false;
}
}else{
testNum=testNum-0.1f;
if(testNum<=inputMin)
{
testTurn=true;
}
}
inputValue=testNum;
}
}
void FixedUpdate()
{
inputTemp = (inputValue - inputMin)/(inputMax - inputMin);
currentReading = inputTemp*(maxReading - minReading) + minReading;
needle.localRotation = Quaternion.Euler(new Vector3(0f,0f,currentReading));
}
}
