Blink
|
|
|
|
Turns on an LED on for one second, then off for one second, repeatedly.
|
|
|
|
The circuit:
|
|
* LED connected from digital pin 13 to ground.
|
|
|
|
* Note: On most Arduino boards, there is already an LED on the board
|
|
connected to pin 13, so you don't need any extra components for this example.
