 Diferentely 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.
