I want to add single tweet with automatically updatation when I port new tweet, new tweet replace with old tweet. I need HTML code. I want to place this code in Facebook tab. I only need tweet text and follow button.
I would recommend using a timeline and limiting the number of tweets displayed to one. See here for how to create a timeline (https://dev.twitter.com/docs/embedded-timelines)
In the html that you get for embed, I would recommend adding attribute data-tweet-limit=1. This will only show only the single latest tweet.Tweets by @twitterapi
