While you did notice that there are many Twitter plugins available out there (both free and paid) which can help you display your latest tweet on your blog. But, what if, I can help you out in achieving this without the use of any plugin.
To achieve this, you can simply paste the following snippet in your theme files, where you want the tweets to be displayed. But make sure you don’t forget to update the code with your username on line 3 with maximum items to display can be defined on line 4.
include_once(ABSPATH . WPINC . '/feed.php');
$rss = fetch_feed('https://api.twitter.com/1/statuses/user_timeline.rss?screen_name=catswhocode');
$maxitems = $rss->get_item_quantity(3);
$rss_items = $rss->get_items(0, $maxitems);
<?php if ($maxitems == 0) echo '<li>No items.</li>';
// Loop through each feed item and display each item as a hyperlink.
foreach ( $rss_items as $item ) : ?>
<a href='<?php echo $item->get_permalink(); ?>'>
<?php echo $item->get_title(); ?>
<?php endforeach; ?>
