Trying to include a file into a wp page

I am trying to call in a carousel. I saved it on its own php file. and am trying to call it in custom page by using


<?php include(ABSPATH . 'carousel.php'); ?>

Not working. Could someone please advs I also tried

<?php include(STYLESHEETPATH.'carousel.php');?>

And that did not work either.
got the error message:

Warning: include(C:\xampp\htdocs\apdSilencers/carousel.php): failed to open stream: No such file or directory in C:\xampp\htdocs\apdSilencers\wp-content\ hemes\apd\home.php on line 12

Warning: include(): Failed opening ‘C:\xampp\htdocs\apdSilencers/carousel.php’ for inclusion (include_path=‘.;C:\xampp\php\PEAR’) in C:\xampp\htdocs\apdSilencers\wp-content\ hemes\apd\home.php on line 12

Never mind all. I got it. In case this helps anyone in the future.
used

<?php get_template_part('carousel', 'page'); ?>

to call it.
You all have an awesome weekend.
