from the others games of velocity and reaction, which are normally based on
Flip-Flops, this exclusive scheme from Esquemas.org uses a PIC
Microcontroller in the interpretations of velocity. The big advantage
of this project is that, besides to demonstrate the fastest, it also
indicates the slowest within four participants through bicoloured Leds,
where the Green Led access indicates the fastest and the blinking red
indicates the slowest. The scheme also has a “headlight” to determine
the start of the game.
