Yes, I have searched and read all the documentation on Twitter use on the Arduino.
I am using a WiFi shield, and I already have all the twitter protocols integrated and have a fully functioning code that posts to twitter, however as I described the question I have is how to run the two different parts of my code (sensor readings, run frequently; and the twitter posting, run periodically) on two different time schedules.
I'm not asking how to send twitter posts, I already have that functioning. As I made clear in my primary post the thing I wanted input on is how to delay time between posts while maintaining a constantly cycling loop function.
