This means that other code can run at the same time without being interrupted by the LED code. The circuit: - Use the onboard LED. - Note: Most Arduinos have an on-board LED you can control. On the UNO, MEGA and
Surprised at the quality of the sample code - what's provided on Intel's site does not work. I have included the fix below in bold (works with
- Use the onboard LED. - Note: 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 ...
/* Blink without Delay Turns on and off a light emitting diode (LED) connected to a digital pin, without using the delay() function. This means that other code can run at the same time without being interrupted by the LED code. The circuit: * Use the onboard LED. * Note: Most Ard...
The second code example is a little more interesting as it switches that pin on and off every 1,000 milliseconds (1 second). The orange LED will blink at one-second intervals…or will it? voidsetup() { //The following code will be executed once when your Arduino turns on. ...
A few seconds after the upload finishes, you should see the on-board LED start to blink. If it does, congratulations! You've gotten your Arduino Yún up-and-running. If you have problems, please see the troubleshooting suggestions.
LED is on but the pin 13 LED is not flashing, it could be that the factory code is not on the chip; follow the instructions inRecipe 1.3to load the Blink sketch onto the board to verify that the board is working. If you are not using a standard board, it may not have a built-...
This sketch receives a digit (single characters 0 through 9) and blinks the onboard LED at a rate proportional to the received digit value: /* * SerialReceive sketch * Blink the LED at a rate proportional to the received digit value */ int blinkDelay = 0; // blink delay stored in th...

Verify that everything works by creating a Blink example (File > Examples > 01.Basics > Blink) and flashing it to your board If you see the built-in LED blinking, you're ready to go! Happy coding! 💻Radio protocol variantsEach board supports a number of different radio protocol stacks...
