you could make your own delay function, like this:

1. void myDelay(int ms){
2.   int time = millis();
3.   while(millis()-time < ms);
4. }

ok, i miss-understood you.
this version works independently to the framerate you set (i dont think its a good idea to set the framerate to 1, for several reasons), which makes the whole sketch more flexible for other interactions and changes.

1. String test[] =
2. {
3.   "hello",
4.   "its",
5.   "me"
6. };
7. int index = 0;
8. int time_last = 0;
9. int time_to_wait = 1000;
10. void setup(){
11.   frameRate(200);
12.   time_last = millis();
13. }
14. void draw(){
15.   background(0);
16.   text(test[index%test.length], width/2, height/2);
17.   manageIndex();
18. }
19. void manageIndex(){
20.   if( millis() - time_last > time_to_wait){
21.     time_last = millis();
22.     index++;
23.   }
24. }

You can also use the frameCount value with a modulo

ie:

frameRate(30);

if(frameCount % 30 == 0){
      index = (index + 1) % your_array.length;
}

Common newbie's error, so I wrote FAQ entries in the wiki:

• What are setup() and draw()?
• I display images in sequence but I see only the last one. Why?
