In this post we see how to create a timer in PowerPoint that runs while on slide presentation mode. The principle is similar to what we saw with Excel timers (see post here: Excel Timer Macros). However, PowerPoint VBA does not support the Application.OnTime method, and therefore we can only run a timer in PowerPoint using either the Timer VBA function or the SetTimer function of the Windows API/User32 library. We will add the timer to a text box at the upper-left corner of the slide. You can download a ready-to-use PowerPoint TimerPPT add-in at the bottom of this article.
