Automatic sentence feed to Twitter

Learnkanji delivers a daily Japanese word over Twitter. I assume the service is man managed.

But is there a way to feed a stack of sentences I store somewhere (140 signs or less) to my Twitter account at fixed interval? I would be in control to tell Start or Stop the feed as needed by sending back a keyword. I would also be able to select the stack I want to be fed with. It would be a kind of remote SRS feeder.

Partial answer : it's called scheduled tweets.
