Link each product to its product_details page in Laravel

In native PHP it takes about 2 minutes to link each product on the page to its product_details page

-- like gives each products an id from the database, and in the details page grab the id from the URL by $_GET and fetch the database info for the same id

Now I am stack doing the same thing in Laravel, can anyone give me hand here please

Here is my code

The route

Route::get('Current_projects', 'ProjectController@currentProjects');
Route::get('projects/projectDetails/{$id}', 'ProjectController@viewProject');

Here is my controller

class ProjectController extends BaseController
{

    /**
     * Display a listing of the resource.
     *
     * @return Response
     */
    public function currentProjects()
    {
        $projects = Projects::all();
        return View::make('projects.currentProjects', ['projects' => $projects]);
    }

    public function viewProject($id)
    {
        $projects = Projects::with('projectDetails')->findOrFail($id);
        return View::make('projects.currentProjects.projectDetails', compact($projects));
    }
}

Here is how I try to link

<a href="{{ URL::to("Current_projects/projectDetails/{$pro->id}") }}"
   class="portfolio-link"
   data-toggle="modal">

Now when I click on any product in the currentProjects

Got Error
