Speed marble game project

An educational project for my mechatronics students, a tube equipped with two LDR sensors to measure the speed of a ball inside the tube.

This project is an educational game made with Arduino board, for teenager students, in which participants have to pull the marble into the tube with their fingers and whoever reaches the maximum speed wins.
In this projects students can learn about speed, measuring light with sensors, measuring time and learn how to make a finite state machine with code.
