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, LEONARDO, MEGA, and ZERO
|
|
it is attached to digital pin 13, on MKR1000 on pin 6. LED_BUILTIN takes care
|
|
of use the correct LED pin whatever is the board used.
|
|
|
|
The MICRO does not have a LED_BUILTIN available. For the MICRO board please substitute
|
|
the LED_BUILTIN definition with either LED_BUILTIN_RX or LED_BUILTIN_TX.
|
|
e.g. pinMode(LED_BUILTIN_RX, OUTPUT); etc.
|
|
|
|
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
|
