The "easiest" way is probably computed sound analysis.3 mikes is a good start.If the question is really about cars, use one ore many microphones with long wires and a mix table , so you can locate noise origin, .The same is possible with wireless mikes.Experienced mechanics don' t really need it, but i admit that it could be useful.Roll Royce mechanics are known to use a stethoscope.Some good Machinists knows about cutting edge state just by the noise.Regards.

Hello!Okay you got it working !For more light,You might try 82 Ohms instead of 100 ohms.Or 3 Batteries witch makes 4.5v instead of 3 v.Or a different type of led , Some make more light than other.When satisfied with light,Then experiment with the probes.Regardsgg
