Do you want to stop the clock continuing past the last page and adding blank pages ad infinitum?
One trick is to reverse all the pages in your flipchart, so that the last page in the sequence is actually page 1.
THEN set the clock from that page to “Turn to previous page”.
When the countdown reaches the real last page, it can’t go any further back and simply stops at that page.
Let us know if this answers your question.
