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, 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 https://www.arduino.cc/en/Main/Products
|
||
|
|
|
||
|
|
This example code is in the public domain.
