# Countdown clock in a break (Help pleease)

Hello everyone,

Thank you so much for creating this forum. I am not familiar with coding and it is difficult to understand. Therefore, I would be greatly grateful if someone could help me in very simple steps.
I am working on creating an experiment using Builder. In the experiment, 60 sentences are individually presented to participants and they are required to judge each sentence. Two things that I wand include in the task using coding that I don’t know how this is done although I have looked at several explanations in the forum. First, after the 20th and 40th sentence , I want participants to take a break for one minute. Second, During the break, I want a countdown clock to appear so that a participant can know how much time is left for the break to end. A photo has been attached. Any help would be very thankful.

In any given routine, there will be a variable called `t`, which is the time (in seconds) since the routine began. So to get a measure of how long is left, you just do `[[TOTAL TIME]] - t` (where `[[TOTAL TIME]]` is how long you want the routine to last).

If you add a Polygon component to the routine, you can set its orientation to be `set each frame`, which means it will calculate whatever value is put in each time the screen refreshes. To make it look like a clock, we’d want to make it very long and thin (size `(0.1, 1)` for example) and have it be `anchor`ed at the bottom center, meaning this is the point it rotates around.

As orientation is from 0-360, we need to transform the time remaining such that when `t` is 0 the orientation is 0 and when `[[TOTAL TIME]] - t` is 0, the orientation is 360. So, the value you would put in the orientation field for your Polygon would be:

``````(t / [[TOTAL TIME]]) * 360
``````

If you want to see this in action, there is a clock face demo in the demos tab in Builder, I also used a similar method when making the clock routine in this Countdown demo:
