How to create the fischertechnik LED REACTION TIME GAME

I play with different educational manipulatives for a living. (Visit www.weirdrichard.com).

An easy-to-build application is the LED REACTION TIME GAME. The robotic controller (in this case the PCS BRAIN) beeps and lights up the first LED as a warning and after a random amount of time will light the second LED. As soon as the second LED is lit, the player will tap the push button sensor. The software will display the amount of time it takes to respond to the light!

This instructable will describe how to create a fischertechnik LED REACTION TIME GAME.
