This is a simple project just to test your reaction. Click the button on the project to check just how fast you can react! The top displayed variable shows the main time, while the *(variable that is displayed below) is the time you take to react. Enjoy! * The variable displayed below has fewer decimal points as for some reason, since you usually do like 'change [variable] by 0.01 then wait 0.01 seconds', it just goes slower for me.
