circuito semáforo

/*

Turns 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, MEGA and ZERO

it is attached to digital pin 13, on MKR1000 on pin 6. LED_BUILTIN is set to

the correct LED pin independent of which board is used.

If you want to know what pin the on-board LED is connected to on your Arduino

model, check the Technical Specs of your board at:
