how to use servo shield?

now i am trying to control 7 servos.each servo should sweep different angles.but i don't know how to programme.pls help me!

Do you want them to sweep to different angles at random intervals? To random angles at the same time? To specific angles at random times? To specific angles at specific times?

The programming for each case will be different. Which one would be most helpful?

specific angles at specific times :)

What angle? Based on what data? When?
