Simulación de dos semáforos, peatones y vehículos.

En esta práctica, hemos avanzado nuestra simulación de un semáforo, esta vez, añadimos el semáforo de los peatones, tuvimos que escribir varios "DigitalWrite" sin "delays" de por medio para que funcionase. El código está copiado al final.

/*

  Blink

  Turns on an LED on for one second, then off for one second, repeatedly.

  Most Arduinos have an on-board LED you can control. On the Uno and

  Leonardo, it is attached to digital pin 13. If you're unsure what

  pin the on-board LED is connected to on your Arduino model, check

  the documentation at http://www.arduino.cc

  This example code is in the public domain.
