En esta primera práctica, hemos creado una luz LED que parpadea cada x tiempo.
El pin 13, tiene una característica especial, tiene al lado el pin ground (GND), de forma que, a demás de que el pin de la placa parpadee, también lo hace el LED que se ponga en el pin 13 y en GND. (Al final del documento se encuentra el código de ambos programas)
En este vídeo, se ve que ambos LEDs, se encienden a la vez a una velocidad alta, esto se debe a que hemos puesto en velocidad de delay 150, si hubiese sido más alta, habrían ido más lentos.
En este otro vídeo, solamente enciende el led integrado en la placa, a una velocidad aún mayor, la velocidad escrita en el delay es de 75.
/*
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.
