I have a working Arduino sketch that posts a tweet each time my garage door goes up or down.
(See: http://www.allmytweets.net/?screen_name=@whatta_nerd )
Question: What would it take to make Arduino delete the oldest tweet prior to posting a new one ?
Modify (add to) Twitter Library ?
I don't see any "delete" capability in it, as it is.
I don't really know where to start.
This sounds like something that someone might have investigated before.
