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.
