FREEBIE: Articulate Storyline simple timer!
I created a Storyline timer, (see Storyline file attached) that cycles between two layers that are each one second to either count-down or you can change it so the timer counts up from a number. If you look at time1 and time2 layers, there are conditions that when the variable called sl_timer, (see screenshot below) reaches 0, time stops. You can add another condition for something to happen, e.g., a text pop-up to appear or audio file to play. Enjoy!
