The Loop block can use data wires for both the loop count and the loop condition. Once you get used to the loop count starting at zero, it’s easy to use it to control the loop. The Timer1 program demonstrates how to use the loop condition to control when the loop finishes. The Timer2 program shows how to use the loop count and a Compare block to control how many times the loop repeats. Finally, the Timer3 program shows how to rearrange the blocks within the loop when you want the loop condition checked at the beginning of the loop. This is useful in situations where you may not want the loop body to be executed at all.
