Let's go with the example using controller name is category

1. Create controller  in Controllers case sensitive name so, create like a example given example :CategoryController.php

//controller path<project_name>/app/Http/Controllers/<controller_name.php>

Example category controller

2. Create view  in views, create like a example :category

//view path<project_name>/resources/views/<view_name>.blade.php

Example category view

//view path<project_name>/resources/views/category.blade.php

3. Add Path to the routes file web.php

Edit web.php 

//route file name<project_name>/routes/web.php

Add this  data to the last 

//here Route::get('/<name_controller>', '<controller_name>@index');

Example category view explain to this how it work with the example

here, we can use any name in the url to call like http://127.0.0.1:8000/category or we can give name anyother like http://127.0.0.1:8000/categories   also, with replace name in route file also.

Route::get('/category', 'CategoryController@index');

4. Example category Add this code to the controller  use as you created your controller name here we created CategoryController.php

//controller path

<project_name>/app/Http/Controllers/CategoryController.php

<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
class CategoryController extends Controller{
    /**     * Show the application dashboard.     *     * @return \Illuminate\Contracts\Support\Renderable     */    public function index()    {        return view('category');    }}

5. Add this code to view in Views  use as you created your view name here we created category.blade.php

//view path

<project_name>/resources/views/category.blade.php

@extends('layouts.app')
@section('content')<div class="container">    <div class="row justify-content-center">        <div class="col-md-8">            <div class="card">                <div class="card-header">Category</div>
                <div class="card-body">                    @if (session('status'))                        <div class="alert alert-success" role="alert">                            {{ session('status') }}                        </div>                    @endif
                    Welcome To the Category!                </div>            </div>        </div>    </div></div>@endsection
