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://arduino.cc
|
||
|
||
This example code is in the public domain.
