Find a simple example of how laravel5.2 controller calls models

For example, there is a table called abc

The structure is id name time

I want to write a model (app/models/abc.php). There is a method called abc_db()
The function is to return the id and name data of the abc table

Then create a controller (app/http/controller/test/TestController.php)
How to call the model in this file and implement var_dump (abc_db() returns data);

Please provide the above examples, thank you very much, I have never understood it, mainly because of eloquent
