Place your mouse pointer on the red stripe. Then move the mouse pointer to the blue stripe. The counter will track your movements across each of the 30 black lines along with the time of day as you pass over each line.

First move the mouse slowly and observe the times. Then click on RESET and observe the times again if you move the mouse more quickly. As you move faster and faster, you will reach a point at which the counter does not have enough resolution to track your movement.

When you are finished with these exercises, click on EXIT to be sure that the program is stopped.
