To open the timer on the Epson Interactive projector, simply click on the screen with your Epson pen. Click the “stopwatch” icon on the bottom of the screen. Then, a stopwatch will pop up. You can either count up or count down by choosing the “up” arrow or “down” arrow. You can also choose the amount of time to count up to or down from. This is a great way to engage your students in learning by giving them timed tasks, or keeping rotations moving, and much more.
