Hi, What exactly are the things in vehicles that display different attributes of the vehicle called? Like for example in a car you have a display that tells you how fast you are going, the temperature of the engine etc.. I have to design one for a project. I suppose I can design a digital one but I think a mechanical one would be easier and cost less. I'm trying to build a low cost one. My plan is to figure out what exactly these things are called, research them, and then go from there. Like I'm not talking about the name of a specific display, like a speedometer, just what is the general thing called that has a glass cover over it, and needle that moves along something with marks on it that people can view to get information. It's a meter of some sort but what kind of meter. I need design one catered one for attributes of a airplane. Thanks, For any help.
