this is a timer.click on the 10sec sprite and it will set the timer to 10 seconds. the same gtoes for the 30sec sprite and the 1min sprite, well, exept that they are 30 seconds and 1 minute. if it doesnt work just re-do the thing.
i got the idea from the timer on my moms phone. (it was the just an average timer) I thought,"this would be easy to make on scratch." Note: i am a beginer on scratch so don't have high expectations.
