LED Reaction Timer

LED Reaction Timer
This project is an updated version of the original reaction timer project described in Len Buckwalter's "Electronic Games & Toys You Can Build" book. The incandescent bulbs and passive components are replaced by a microcontroller and LEDs.

Step 1The Original Reaction Timer

The Original Reaction Timer
This is the original reaction timer game. The purpose of the game is to see who has the fastest reaction time. A golf ball is placed at the top of the rail and allowed to roll downhill until it hits a stop. The first person to press his button AFTER the ball hits the stop is the winner. If a player presses his button before the ball reaches the end, he loses.

Yes, please do post the program. This looks like something that I can use in my high school physics class to demonstrate reaction times.
